abstract = {The ignition of an atmospheric pressure laminar premixed methane/air mixture by Nanosecond Repetitively Pulsed (NRP) discharges in a pin-pin configuration is studied using fully coupled plasma-combustion numerical simulations. These simulations are performed using the AVIP code specifically developed for low temperature plasma modeling and coupled to the combustion code AVBP. A reduced chemical scheme for plasma-assisted combustion previously derived and validated is used to investigate the effect of the frequency of NRP discharges and the benefits of their chemical enhancement. It is observed that the induced shock wave produced by strong discharges is of major importance for ignition and can lead to quenching of the ignition kernels through strong induced recirculation of gases. Increasing the frequency of the discharges reduces this effect by depositing less energy at each discharge and accumulating energy more homogeneously between the electrodes, leading to a faster and more stable ignition. The minimum energy necessary to ignite decreases with increasing frequency and at the highest studied frequency (100 kHz) ignition has been achieved with 30% less energy than with a single-pulse discharge.},

abstract = {Pure methane-oxygen mixtures in liquid rocket engines lead to extreme pressure and temperature conditions that are prohibitive for most of the experimental setups. Hence, there is very little data on such flames in the literature, especially concerning the laminar flame speed , often limited at atmospheric pressure. The recent development of methalox rocket engines, which design process often requires CFD calculations, brings this lack of data to the forefront. Indeed, the CFD simulations require valid chemical schemes in the real operating conditions. To address this problem, flame measurements have been performed in a special isochoric combustion chamber with full optical access (OPTIPRIME) developed at ICARE. An extensive database in conditions never tested before is generated for several equivalence ratios, temperature and pressure ranges. Multiple chemical mechanisms were then compared to those results, showing various levels of agreement. Hence, the best mechanism from the literature on OPTIPRIME results and other literature experimental data was selected. A sensitivity analysis was performed to identify key chemical reactions controlling the flame speed. These key reactions could later be tuned by an optimization process to perfectly match the experimental results. Finally, additional measurements were performed in order to develop a =f(,) correlation to build a future flame speed database under rocket engines relevant conditions.}}

abstract = {This work uses Large Eddy Simulation (LES) combined with an accurate chemical description to predict soot formation in a turbulent spray flame burning real fuel at atmospheric conditions. Understanding and being able to predict soot formation in practical configurations burning complex liquid fuel is essential for the design of engines meeting present and future environmental requirements. The prediction of soot formation with numerical simulations has been mostly limited to academic configurations burning light gaseous fuel. This is explained by the numerical cost of (i) the fuel oxidation chemistry including soot precursors like Polycyclic Aromatic Hydrocarbons (PAH), and (ii) the modeling of two dispersed phases, i.e., the liquid fuel spray and the soot particles. In this work, an Analytically Reduced Chemistry (ARC) for real fuels is proposed to allow a direct integration of accurate combustion chemistry including PAH in the compressible LES solver AVBP. The ARC model is coupled with a Lagrangian particle tracking approach for both the fuel droplets and the soot, including for the latter the description of the complex physical and chemical processes driving the particle evolution. Validation is first performed in a one-dimensional ethylene/air flame configuration, experimentally studied in the literature at several operating points. The numerical profiles of both the soot volume fraction and the soot diameter are in good agreement with measurements. This allows to apply the LES methodology to the sooting swirled turbulent liquid JetA-1/air combustor measured at UTIAS. Very satisfying predictions for both the flow dynamics and the soot production are obtained. The analysis of the results brings valuable new insights on the interaction between fuel droplets, turbulent combustion, PAH and soot evolution in such complex flames.}}

abstract = {Large Eddy Simulations of the realistic liquid fueled gas turbine combustor LOTAR operated at ONERA are performed for two fuels; a conventional JetA-1 and an alternative alcohol to jet fuel At-J, each modeled by a 3-component formulation. JetA-1 is composed of n-dodecane, methyl-cyclohexane and xylene each corresponding to the major hydrocarbon families found in real fuel. At-J is a synthetic drop in fuel composed of only branched chain alkanes, iso-octane, iso-dodecane and iso-hexadecane. Analytically Reduced Chemistry and multicomponent spray evaporation model coupled to the dynamic thickened flame turbulent combustion model are employed to understand the processes involved in turbulent spray flames in the LOTAR configuration. The objectives are to predict and understand the potential effects of staged vaporisation and consumption of the fuel components, and their impact on the spray flame structures. Simulations confirm the role of preferential evaporation in establishing and stabilising the reaction zone. JetA-1 evaporation zones extend deep into the rich burnt gasses resulting in a combustion regime with the possibility of droplet clusters burning individually. At-J which is more volatile, leads to complete combustion with the majority occurring due to the premixed lean reactions of the smaller pyrolysed components. The need to further include models capable of identifying and handling combustion regimes encountered in such spray flames is hence highlighted. This work is intended as a starting point for improving multicomponent spray modelling and requires additional experimental data for validation.}}

abstract = {Modeling turbulent non-premixed combustion remains a challenge in the context of Large Eddy Simula- tion (LES) in complex geometries and for realistic conditions, taking into account all physical phenomena impacting the flame such as heat loss, dilution, or liquid fuel atomization and evaporation. In this work, the Thickened Flame concept, which allows to resolve the flame front on the LES grid while preserving the consumption speed, and initially derived for premixed combustion, is adapted to diffusion flames. It is demonstrated that the concept holds for these flames, with however, a different formulation of the model due to but their specific nature and properties. In particular, in the high-Damköhler regime, the thickening factor is applied only to the diffusion coefficients. The behavior of thickened diffusion flames is illustrated on laminar steady strained flames for both simple and complex chemistry, showing how the Thickened Flame concept applies. Based on these re
sults, an expression for the thickening factor related to mesh coarsening is derived. For a complete turbulent combustion model, the thickening factor should also describe the sub-grid scale flame-turbulence interaction, which is left for future work.},

abstract = {Methane–oxygen burning is considered for many future rocket engines for practicality and cost reasons. As this combustion is slower than hydrogen–oxygen, flame ignition and stability may be more difficult to obtain. To address these questions, numerical simulation with realistic chemistry is appropriate. However the high pressure and turbulence intensity encountered in rocket engines enhance drastically the stiffness of methane oxy-combustion. In this work, Analytically Reduced Chemistry (ARC) is proposed for accurate chemistry description at a reasonable computational cost. An ARC scheme is specifically derived for typical rocket engine conditions. It is validated by comparison with its parent skeletal mechanism on a series of laminar flames. Then the numerical stiffness of chemistry is overcome with an original approach for time integration, allowing to run simulations close to the acoustic time step whatever the chemical stiffness. It is demonstrated on laminar cases that the flame structure is well preserved, and that numerical stability is ensured while decreasing significantly the computational cost. The performance of ARC with the fast time integration method is finally demonstrated in a 3D Large-Eddy Simulation of a lab-scale Liquid Rocket Engine combustion chamber, where a detailed flame analysis is conducted.},

abstract = {Although a lot of research and development has been done to understand and master the major physics involved in cryogenic rocket engines (combustion, feeding systems, heat transfer, stability, efficiency, etc.), the injection system and wall heat transfer remain critical issues due to complex physics, leading to atomization in the subcritical regime and the interactions of hot gases with walls. In such regimes, the fuel is usually injected through a coaxial annulus and triggers the atomization of the central liquid oxidizer jet. This type of injector is often referred to as air-assisted, or coaxial shear, injector, and has been extensively studied experimentally. Including such injection in numerical simulations requires specific models as simulating the atomization process is still out of reach in practical industrial systems. The effect of the injection model on the flame stabilization process and thus on wall heat fluxes is of critical importance when it comes to the design of wall-cooling systems. Indeed, maximizing the heat flux extracted from the chamber can lead to serious gain for the cooling and feeding systems for expander-type feeding cycles where the thermal energy absorbed by the coolant is converted into kinetic energy to drive the turbo-pumps of the feeding system. The methodology proposed in this work to numerically predict the flame topology and associated heat fluxes is based on state-of-the-art methods for turbulent reactive flow field predictions for rocket engines, including liquid injection, combustion model, and wall treatment. For this purpose, high-fidelity Large Eddy Simulation Conjugate Heat Transfer, along with a reduced kinetic mechanism for the prediction of H2/O2 chemistry, liquid injection model LOx sprays, and the use of a specific wall modeling to correctly predict heat flux for large temperature ratio between the bulk flow and the chamber walls, is used. A smooth and a longitudinally ribbed combustor configuration from JAXA are simulated. The coupling strategy ensures a rapid convergence for a limited additional cost compared to a fluid-only simulation, and the wall heat fluxes display a healthy trend compared to the experimental measurements. An increase of heat transfer coherent with the literature is observed when walls are equipped with ribs, compared to smooth walls. The heat transfer enhancement of the ribbed configuration with respect to the smooth walls is coherent with results from the literature, with an increase of around +80% of wall heat flux extracted for the same chamber diameter.},

abstract = {The resolution of the Poisson equation is usually one of the most computationally intensive steps for incompressible
fluid solvers. Lately, DeepLearning, and especially convolutional neural networks (CNNs), has been introduced to
solve this equation, leading to significant inference time reduction at the cost of a lack of guarantee on the accuracy of
the solution.This drawback might lead to inaccuracies, potentially unstable simulations and prevent performing fair
assessments of the CNN speedup for different network architectures. To circumvent this issue, a hybrid strategy is
developed, which couples a CNN with a traditional iterative solver to ensure a user-defined accuracy level. The CNN
hybrid method is tested on two flow cases: (a) the flow around a 2D cylinder and (b) the variable-density plumes with
and without obstacles (both 2D and 3D), demonstrating remarkable generalization capabilities, ensuring both the
accuracy and stability of the simulations. The error distribution of the predictions using several network architectures
is further investigated in the plume test case. The introduced hybrid strategy allows a systematic evaluation of the
CNN performance at the same accuracy level for various network architectures. In particular, the importance of
incorporating multiple scales in the network architecture is demonstrated, since improving both the accuracy and the
inference performance compared with feedforward CNN architectures. Thus, in addition to the pure networks’
performance evaluation, this study has also led to numerous guidelines and results on how to build neural networks

abstract = {SAFRAN Helicopter Engines has developed the spinning combustion technology in which the burnt gases from one injector travel tangentially along the combustor annulus towards the neighboring injectors. Compared to a conventional design, this arrangement modifies the ignition process, which is a critical phase for aeroengines. In order to understand the ignition process in this technology, experiments and Large-Eddy Simulation (LES) have been performed in a cylindrical combustion chamber where the flow is injected tangentially (named Radius chamber). Three cases are considered with different strain and turbulence levels representative of real combustor flows. Micro calorimetry and the Background-Oriented Schlieren technique allows for detailed temporal measurements of energy deposited in the flame kernel. Pressure measurement and Schlieren imaging are used to study the flame propagation. LES are performed with a 19-species and 184-reactions analytically-reduced chemistry together with the thickened flame approach allowing the description of the first instants of ignition in a quasi-DNS mode and ensuing flame propagation. Both a static and dynamic formulations of the wrinkling factor to describe sub-grid scale chemistry-turbulence interaction are used. Results show that LES is able to capture the flame kernel formation and trajectory as well as the time to reach maximum pressure within an error of 10% when using a dynamic formulation. On the other hand, the static formulation of the wrinkling factor predicts the time for maximum pressure within a maximum error of 20%.},

abstract = {Explicit time integration based CFD solvers suffer from restriction on the maximum allowable time step computed from the well known Courant-Friedrichs-Lewy (CFL) stability criterion. This restriction poses severe challenge in carrying out large eddy simulation (LES) of reactive and non-reactive flows, where the grid resolution is fine. The challenge of restricted time step is further augmented when dealing with large computational domains that pose a wide disparity in the system time scales. In this study, a numerical methodology is presented based on local time stepping in an overset grid framework. The attainable speedup is found to be a function of the ratio of time steps used in the sub-domains and the ratio of the number of computational degrees of freedom. The method is analyzed using global spectral analysis (GSA) and shows excellent agreement in solution accuracy with the conventional explicit time integration based solver. The impact of local time stepping on the order of accuracy and global conservation properties are also presented. This method is then applied to simulate three flow test cases to demonstrate the ability of the method to reproduce the first and second-order turbulent statistics at reduced computational time.},

In the present work, we propose an innovative methodology that uses high-fidelity numerical simulations of turbulent reactive flows and artificial intelligence for the generation of surrogate models. The surrogate models that were generated and analyzed are deep learning networks trained on a dataset of 100 large eddy simulations of a single-shear coaxial injector chamber. The design of experiments was created considering three design parameters: chamber diameter, recess length, and oxidizer–fuel ratio. The paper presents the methodology developed for training and optimizing the data-driven models. Fully connected neural networks (FCNNs) and U-Nets were utilized as surrogate-modeling technology. Eventually, the surrogate models for the global quantity, average, and root mean square fields were used in order to analyze the impact of the length of the post’s recess on the performances obtained and the behavior of the flow.}}

enables to evaluate the numerical approach by comparison with measurements, and to analyse the influence of inter-injector spacing on both the flow dynamics and the local fuel distribution. Second, the comparison of numerical fully transient ignition sequences with experimental data shows that LES recovers the inter-injector spray propagation features found in the experiment such as flame propagation modes from radial to progressively arc-like, and total ignition time delay. However due to important pre-evaporation, liquid fuel does not significantly impact the overall ignition process, which exhibits the same driving mechanisms as in purely gaseous
flows.},

abstract = {A computational study of one dimensional multicomponent laminar Jet-A/air spray flames is presented. The objective is to understand the effect of various spray parameters (diameter, droplet velocity, liquid loading) on the spray flame structure and propagation. Simulation of the Eulerian gas phase is coupled with a Lagrangian tracking of the dispersed liquid phase. Jet-A surrogate of n-dodecane, methyl-cyclohexane and xylene is considered. A discrete multicomponent model for spray vaporization is used along with an analytically reduced chemistry for computing the gas phase reactions. Both overall lean and rich cases are examined and compared with existing literature for single component spray flames. The preferential evaporation effect, unique to multicomponent fuels causes a variation of fuel vapor composition on both sides of the flame front and this has a direct impact on the spray flame structure and propagation speed. In the rich cases, multiple flame structures exist due to the staged release of vapors across the reactive zone. Spray flame speed correlations proposed for single component fuels are extended to the multicomponent case, for both zero and high relative velocity between the liquid and the gas. The correlations are able to accurately predict the effective equivalence ratio at which the flame burns and hence the laminar spray flame speeds of multicomponent fuels for all cases studied in this work.},

abstract = {Ignition capability is a critical design constraint for aeronautical gas turbines. However the current trend toward overall lean burn is detrimental to the engine ignition and relight and the ignition system must be adapted to ensure a fast and reliable light-round in all circumstances. As ignition is a stochastic phenomenon, the optimization of an ignition system requires to build ignition probability maps, which is difficult and costly with either experiment or numerical simulation as both require many tests. This work proposes a model to predict the ignition probability map, knowing only flow statistics in non-reacting conditions, i.e., with only one test. The originality of the model is to construct statistics of the flame kernel trajectory, which are then combined with local flow indicators to evaluate the ignition probability at the considered sparking location. Application to a swirled burner operated in premixed, non-premixed and spray combustion modes illustrates the model concepts and demonstrates its ability to recover the experimental ignition map with good accuracy.},

abstract = {During the ignition of a swirled single-injector combustor, two phases have been identified experimentally. In the first, the flame penetrates the injection unit, while in the second, the flame lifts off after a substantial delay before stabilizing at a distance from the injector. This transient phenomenon is investigated using Large Eddy Simulations based on an Euler–Lagrange description of the liquid spray, an energy deposition model to mimic ignition, and the thickened flame combustion model. It is shown that the initial penetration of the flame in the injector unit is linked with the positive pressure excursion induced by the rapid volumetric expansion of burnt gases. This sudden expansion is itself due to the fast increase in heat release rate that occurs during the initiation of the process. The corresponding positive and negative pressure disturbances induce a rapid reduction of the mass flow rate through the injector, followed by an acceleration of the flow and a return to the nominal value. It is also shown that the flame root disappears after another delay, which results in the flame edge lifting and stabilization at a distance from the injector exhaust corresponding to steady operation of the device. The relatively long delay time before this liftoff takes place is found to correspond to the residence time of the cooled burnt gases in the vicinity of the chamber walls, which are ultimately entrained by the internal recirculation zone and quench the lower flame foot.Combustion, Combustion chambers, Ejectors, Evaporation, Flames, Heat, Ignition, Temperature, Flow (Dynamics), Large eddy simulation, Gases, Pressure, Fuels, Drops, Sprays},

abstract = {Liquid injection systems play a key role in the control of flame stability and reduction of pollutant emissions in aircraft engines. However, the disintegration process of the liquid fuel is not completely understood. In that context, direct numerical simulations can be helpful but tend to be very costly. Indeed, they require high spatial resolution to accurately capture complex phenomena such as liquid-gas interface instabilities and primary atomization process with liquid bags, ligaments, and droplets formation. This paper presents a computational study of a prefilming atomizer where relevant di-mensionless parameters are chosen to reproduce realistic conditions while limiting CPU cost. The experiment under study is an academic configuration from KIT-ITS in which a liquid film is injected along a prefilmer plate surrounded by high-speed air flow. The simulation has been performed with the incompressible solver NGA using a volume of fluid method coupled with a piecewise linear interface calculation technique for interface reconstruction. Qualitative and quantitative analyses are carried out and show very good agreement between simulation and experiment. The main physical phenomena such as film instabilities, liquid accumulation process at the prefilmer edge, and primary breakup mechanisms are well recovered by the simulation and in agreement with the experiment. A consistent method to compare both the experiment and the numerical simulation based on frame analysis is developed to extract the droplet diameter distribution. The resulting size distribution evaluated from simulation is shown to be in good agreement with experimental data validating our proposed methodology to reduce computational cost. },

abstract = {The design challenge of reliable lean combustors needed to decrease pollutant emissions has clearly progressed with the common use of experiments as well as large eddy simulation (LES) because of its ability to predict the interactions between turbulent flows, sprays, acoustics, and flames. However, the accuracy of such numerical predictions depends very often on the user's experience to choose the most appropriate flow modeling and, more importantly, the proper spatial discretization for a given computational domain. The present work focuses on the last issue and proposes a static mesh refinement strategy based on flow physical quantities. To do so, a combination of sensors based on the dissipation and production of kinetic energy coupled to the flame-position probability is proposed to detect the regions of interest where flow physics happens and grid adaptation is recommended for good LES predictions. Thanks to such measures, a local mesh resolution can be achieved in these zones improving the LES overall accuracy while, eventually, coarsening everywhere else in the domain to reduce the computational cost. The proposed mesh refinement strategy is detailed and validated on two reacting-flow problems: a fully premixed bluff-body stabilized flame, i.e., the VOLVO test case, and a partially premixed swirled flame, i.e., the PRECCINSTA burner, which is closer to industrial configurations. For both cases, comparisons of the results with experimental data underline the fact that the predictions of the flame stabilization, and hence the computed velocity and temperature fields, are strongly influenced by the mesh quality and significant improvement can be obtained by applying the proposed strategy.

abstract = {In the framework of wall-modeled large-eddy simulation (WMLES), the problem of combining sub-grid scale (SGS) models with the standard wall law is commonly acknowledged and expressed through multiple undesired near-wall behaviors. In this work, it is first observed
that the static Smagorinsky model predicts efficiently the wall shear stress in a wall-modeled context, while more advanced static models like
wall-adapting local eddy (WALE) viscosity or Sigma with proper cubic damping fail. It is, however, known that Smagorinsky is overall too
dissipative in the bulk flow and in purely sheared flows, whereas the two other models are better suited for near-wall flows. The observed difficulty comes from the fact that the SGS model relies on the filtered velocity gradient tensor that necessarily comes with large errors in the
near-wall region in the context of WMLES. Since the first off-wall node is usually located in the turbulent zone of the boundary layer, the turbulent structures within the first cell are neither resolved by the grid nor represented by the SGS model, which results in a lack of turbulent
activity. In order to account for these subgrid turbulent structures, a stochastic forcing method derived from Reynolds-averaged
Navier–Stokes (RANS) turbulence models is proposed and applied to the velocity gradients to better estimate the near-wall turbulent viscosity while providing the missing turbulent activity usually resulting from the WMLES approach. Based on such corrections, it is shown that
the model significantly improves the wall shear stress prediction when used with the WALE and Sigma models},

abstract = {The resolution of the Poisson equation is usually one of the most computationally intensive steps for incompressible fluid solvers. Lately, Deep Learning, and especially Convolutional Neural Networks (CNN), has been introduced to solve this equation, leading to significant inference time reduction at the cost of a lack of guarantee on the accuracy of the solution. This drawback might lead to inaccuracies and potentially unstable simulations. It also makes impossible a fair assessment of the CNN speedup, for instance, when changing the network architecture, since evaluated at different error levels. To circumvent this issue, a hybrid strategy is developed, which couples a CNN with a traditional iterative solver to ensure a user-defined accuracy level. The CNN hybrid method is tested on two flow cases, consisting of a variable-density plume with and without obstacles, demostrating remarkable generalization capabilities, ensuring both the accuracy and stability of the simulations. The error distribution of the predictions using several network architectures is further investigated. Results show that the threshold of the hybrid strategy defined as the mean divergence of the velocity field is ensuring a consistent physical behavior of the CNN-based hybrid computational strategy. This strategy allows a systematic evaluation of the CNN performance at the same accuracy level for various network architectures. In particular, the importance of incorporating multiple scales in the network architecture is demonstrated, since improving both the accuracy and the inference performance compared with feedforward CNN architectures, as these networks can provide solutions 1 10-25 faster than traditional iterative solvers. },

A more wrinkled flame is observed at downstream locations when using the COFFEE mechanism, demonstrating stronger flame/turbulence interaction. This flame also has a significantly lower acoustic power even though it features more acoustic output at high frequencies. The former is shown to arise from lower fluctuations of the heat release rate, whilst the latter is caused by the COFFEE mechanism creating more wrinkled flame surfaces. These results suggest that the accurate simulation of the noise emitted by turbulent premixed flames requires a chemical mechanism that ensures two main features: the heat release rate profile is important for modelling the overall sound amplitude and low frequency acoustics, whilst the flame/turbulence interaction impacts the higher frequency sound.},

abstract = {Flames diluted by combustion products can reduce emissions such as Carbon Monoxide (CO) and Nitrogen Oxides (NO) in industrial applications. In gas turbines, these flames are confined in a combustor and can interact with relatively cold walls. This interaction can quench the flame, producing incomplete combustion products. In this study, Flame-Wall Interaction (FWI) for methane/air flames diluted by hot combustion products is investigated using direct numerical simulation. A three-Dimensional (3D) turbulent V-flame in a channel with isothermal hot and cold walls is simulated.
It is shown that a main reaction zone in the central region between two walls supported by periodic bulk ignition events changes the position of volumetric reaction zones where CO is formed. The cold wall leads to a longer flame, thereby having disproportionately large contribution to the exhaust CO. Near-wall turbulence-flame interaction creates wrinkled and streaky flame surfaces, and localises the near-wall CO distribution. High mean CO mass fraction develops in the free-stream while a high magnitude of the peak RMS CO mass fraction is present closer to the wall. It is also shown that one-dimensional flame solutions can reasonably describe the changes of CO mass fraction as a function of temperature in the free-stream region and some parts of the near-wall region but not close to the wall. Turbulent mixing and diffusion effects contribute to this deviation. The results highlight the complexities involved in CO modelling for diluted flames and set a benchmark for future work.

abstract = {With the increased interest in electric propulsion for space applications,
a wide variety of electric thrusters have emerged. For many years, Hall e ect thrusters
have been the selected technology to sustain observation and telecommunication satel-
lites thanks to their advantageous service lifetime, their high speci c impulse and high
power to thrust ratio. Despite several studies on the topic, the Hall thruster electric
discharge remains still poorly understood. With the increase of available computing
resources, numerical simulation becomes an interesting tool in order to explain some
complex plasma phenomena. In this paper, a
uid model for plasma
ows is presented
for the numerical simulation of space thrusters. Fluid solvers often exhibit strong hy-
potheses on electron dynamics via the drift-di usion approximation. Some of them use
a quasi-neutral assumption for the electric eld which is not adapted near walls due
to the presence of sheaths. In the present model, all these simpli cations are removed
and the full set of plasma equations is considered for the simulation of low-temperature
plasma
ows inside a Hall thruster chamber. This model is implemented in the un-
structured industrial solver AVIP, ecient on large clusters and adapted to complex
geometries. Electrical sheaths are taken into account as well as magnetic eld and
majors collision processes. A particular attention is paid on a precise expression of the
di erent source terms for elastic an inelastic processes. The whole system of equations
with adapted boundary conditions is challenged with a simulation of a realistic 2D
r-z Hall thruster con guration. The full-
uid simulation exhibits a correct behavior
of plasma characteristics inside a Hall e ect thruster. Comparisons with results from
the literature exhibit a good ability of AVIP to model the plasma inside the ionization
chamber. Finally a speci c attention was brought to the analysis of the thruster per-
formances.},

abstract = {A generic and self-adapting method for flame front detection and thickening is presented. This approach relies solely on geometric considerations and unlike previous thickening methods does not need any parameterization nor preliminary calibration. The detection process is based on the analysis of the curvature of a test function, associating a bell-curve shape to a flame front. Once the front is located, the front thickness is also evaluated from the test function, allowing (1) a thickening restricted to under-resolved flame regions, (2) a self-adapting thickening of the front. The thickening process is finally applied to the detected front, over a normal-to-the-flame distance, using a Lagrangian point-localization algorithm. The method was developed and implemented in an unstructured and massively parallel environment and is therefore directly usable for the computation of complex configurations. Three test cases are presented to validate the methodology, ranging from a
one-dimensional laminar premixed flame to the VOLVO turbulent premixed flame.},

abstract = {Understanding the physical mechanisms governing scientific and engineering systems requires performing experiments. Therefore, the construction of the Design of Experiments (DoE) is paramount for the successful inference of the intrinsic behavior of such systems. There is a vast literature on one-shot designs such as low discrepancy sequences and Latin Hypercube Sampling (LHS). However, in a sensitivity analysis context, an important property is the stochasticity of the DoE which is partially addressed by these methods. This work proposes a new stochastic, iterative DoE – named KDOE – based on a modified Kernel Density Estimation (KDE). It is a two-step process: (i) candidate samples are generated using Markov Chain Monte Carlo (MCMC) based on KDE, and (ii) one of them is selected based on some metric. The performance of the method is assessed by means of the C2-discrepancy space-filling criterion. KDOE appears to be as performant as classical one-shot methods in low dimensions, while it presents increased performance for high-dimensional parameter spaces. It is a versatile method which offers an alternative to classical methods and, at the same time, is easy to implement and offers customization based on the objective of the DoE.},

Large Eddy Simulation (LES) is used to simulate the turbulent flow in a wall-resolved periodic channel configuration, heated via a uniform heat flux at the wall. In order to enhance the heat exchange with the flow, the inner surface of the channel features rounded rib. This however increases the pressure loss, and an optimum shape of the rib is to be found. The rib pitch and height as well as rib discontinuities are the geometrical parameters to optimize, allowing a wide variety of inner wall roughness. To limit the number of LES, the optimization procedure is based on a surrogate model constructed from Gaussian Process Regression and adaptive resampling with the Efficient Global Optimization (EGO) method [1]. The optimization consists in the maximization of the cost function proposed by Webb and Eckert [2], which aims at maximizing the heat transfer efficiency for similar pumping power. Results show that a rib induced swirling motion in the near wall region significantly decreases the heat transfer efficiency, leading to an optimum roughness shape featuring large and multiple discontinuities. Moreover, the efficiency of helically dimpled tubes is also found sensitive to the shape of the transitions between the discontinuous parts of the rib. Smoother transitions lead to lower pressure loss but also to lower heat transfer due to smaller recirculation zones.},

The observation of ignition sequences in a representative lab-scale combustion chamber, from both experiment and numerical simulation, reveals a variety of scenarios leading to success or failure. In particular the occurrence of quenching events after the successful creation of a kernel flame is a key mechanism for the outcome of the sequence. A first analysis leads to a classification of ignition/extinction scenarios, based on similar time evolutions and trajectories of the flame kernel. It is found that this classification is much dependent on the sparking location. Then a deeper analysis allows to decompose all scenarios in a succession of more simple, generic mechanisms which are independent of the geometry. This decomposition is a useful tool to describe, understand and predict ignition sequences, being successful or not, in any combustion chamber geometry.},

During the ignition process, a spark plug delivers a very short and powerful electrical discharge to the mixture. A plasma is first created before a flame kernel propagates. The present work focuses on this still misunderstood first instants of ignition, i.e., from the sparking to the flame kernel formation. 3D Direct Numerical Simulations of propane-air ignition sequences induced by an electric discharge are performed on a simple anode-cathode set-up. An Analytically Reduced Chemistry (ARC) including 34 transported species and 586 irreversible reactions is used to describe the coupled combustion and plasma kinetics. The effect of plasma chemistry on the temperature field is found to be non-negligible up to a few microseconds after the spark due to endothermic dissociation and ionization reactions. However, its impact on the subsequent flame kernel development appears to be weak in the studied configuration. This tends to indicate that plasma chemistry does not play a key role in ignition and may be omitted in numerical simulations.},

abstract = {High-fidelity numerical simulations are used to study flame root stabilization mechanisms of cryogenic flames, where both reactants (O2 and CH4 ) are injected in transcritical conditions in the geometry of the laboratory scale test rig Mascotte operated by ONERA (France). Simulations provide a detailed insight into flame root stabilization mechanisms for these diffusion flames: they show that the large wall heat losses at the lips of the coaxial injector are of primary importance, and require to solve for the fully coupled conjugate heat transfer problem. In order to account for flame–wall interaction (FWI) at the injector lip, detailed chemistry effects are also prevalent and a detailed kinetic mechanism for CH4 oxycombustion at high pressure is derived and validated. This kinetic scheme is used in a real-gas fluid solver, coupled with a solid thermal solver in the splitter plate to calculate the unsteady temperature field in the lip. A simulation with adiabatic boundary
conditions, an hypothesis that is often used in real-gas combustion, is also performed for comparison. It is found that adiabatic walls simulations lead to enhanced cryogenic reactants vaporization and mixing, and to a quasi-steady flame, which anchors within the oxidizer stream. On the other hand, FWI simulations produce
self-sustained oscillations of both lip temperature and flame root location at similar frequencies: the flame root moves from the CH 4 to the O 2 streams at approximately 450 Hz, affecting the whole flame structure.},

Velocity profiles and wall temperatures were measured at the Von Karman Institute (VKI) using

(2018). Comparisons show that the numerical methodology gives accurate results in terms of mean
and fluctuating velocity fields as well as the correct friction drag. The wall temperature profile is also
in good agreement with the experiment. The rib induces a large recirculation zone immediately downstream,
with a reattachment point occurring a few rib heights farther downstream. The helical shape
of the rib also induces a strong swirling motion close to the wall. The pressure drop is found equal to
3:37 Pa/m and is mostly due to the pressure drag. Maximum heat transfer is found just upstream of
the reattachment point and on top of the ribs, which is in good agreement with experimentally obtained
values. The mean Nusselt number in the ribbed tube is found 2.3 times higher than in a smooth tube confirming
the positive impact of such geometry on heat transfer.},

abstract = {Reacting numerical simulations today are often based on either fitted global reaction schemes, comprised of a few empirical reactions, or pre-tabulated laminar flame solutions computed with detailed chemistry. Although both methods can accurately predict global quantities such as laminar flame speed and burnt gas composition, they have significant limitations. In particular, neither are able to directly and adequately describe the complexity of pollutant chemistry. In the context of reducing harmful emissions of the next generation of aeronautical combustors, however, including these needed additional kinetic details in combustion simulations is becoming essential. Direct integration of detailed chemistry in accurate turbulent combustion models is not a viable option in the foreseeable future, because of excessive computational demands and numerical stiffness. In this context, Analytically Reduced Chemistry (ARC) represents an attractive compromise between accuracy and effic
iency, and is already employed in relatively complex Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES). ARCs are knowledge-based compact mechanisms retaining only the most relevant kinetic information as extracted directly, and without fitting, from detailed chemical models using specialized reduction techniques (important species identification through graph search, lumping of species with similar features, short-living species identification, etc.). In recent years, several multi-step efficient and automated reduction tools have been developed, enabling the easy generation of ARCs with minimum input and knowledge from the user. The main objective of this paper is to present a review of ARCs for fuels ranging from methane to aviation kerosene surrogates, recently derived with such a multi-step automated reduction tool: YARC. Information about the applicability and range of validity of each derived mechanism are given, along with further references. Each on
e was specifically derived to be convenient to use in CFD; in particular, the stiffness was regarded as a key factor and the final number of transported species never exceeds thirty. In a final section, the great potential of the methodology is illustrated in a multi-phase, reactive LES application where the fuel is a real multi-component transportation fuel. To that end, an ARC based on a Jet A described by the novel Hybrid Chemistry (HyChem) approach is coupled with the Dynamically Thickened Flame LES (DTFLES) model and directly integrated into the LES solver AVBP. A Lagrangian spray description is used. Results are compared to experimental data in terms of temperature and major species (CO 2 , H 2 O, CO, NO) mass fractions, leading to very satisfying results.},

abstract = {Large Eddy Simulation (LES) with direct integration of reduced chemical kinetics including NO chemistry is performed on the Sandia flame D. This approach allows a detailed analysis of the flame structure and pollutant formation. The Analytically Reduced Chemistries (ARCs) are obtained using Directed Relation Graph method with Error Propagation (DRGEP) and Quasi-Steady-State (QSS) approximation. Two ARCs containing both 22 species are derived for methane–air oxidation, from GRI 2.11 and GRI 3.0 detailed mechanisms. They correctly predict fuel consumption speed, as well as NO and CO concentrations in laminar premixed and non-premixed flames at atmospheric conditions. It is found that the NO production strongly depends on the detailed mechanism, being significantly higher with GRI 3.0 in rich premixed flames and in diffusion flames. The two ARCs are then used in highly-resolved LES of the Sandia flame D. The numerical results are in very good agreement with the experiment in terms of aerodynamics, mixture fraction and temperature profiles. The CO concentration is also well predicted with the two ARCs. For NO, a satisfactory agreement with the measurements is obtained with the ARC based on GRI 2.11, while a significant over-prediction is obtained with the GRI 3.0-based ARC, consistently with the differences observed in laminar cases between the two GRI versions. A detailed investigation of the flame structure including a comparison with reference laminar flames reveals that the flame structure is essentially non-premixed. The presence of the pilot jet alters the mixing process, leading to a flame structure that falls between two extreme non-premixed combustion regimes corresponding to the interaction of the rich central jet with either the hot gases from the pilot, or the coflow of fresh air. The associated laminar diffusion flamelets indicate that this particular flame structure influences the formation of pollutants, with a strong impact on CO production.},

Combined with the Dynamic Thickened Flame model (DTFLES), the ARC-LES approach does not require specific flame modeling assumptions and naturally adapts to any flow or geometrical complexity. To demonstrate the added value of the ARC methodology for the prediction of flame structures in various combustion regimes, including formation of intermediate species and pollutants, it is compared to a standard tabulation method (FPI). Comparisons with available measurements show an overall good agreement with both chemistry approaches, for the velocity and temperature fields. However, the flame structure is shown to be much improved by the inclusion of explicitly resolved chemistry with ARC. In particular, the ability of ARC to respond to strain and curvature, and to intrinsically contain CO/O2 chemistry greatly influences the flame shape and position, as well as important species production and consumption throughout the combustion chamber. Additionally, since both chemistry descriptions are able to account for intermediate species such as OH and C2H2, soot formation is also investigated using a two-equations empirical soot model with C2H2 as the sole precursor. It is found that, in the present configuration, this precursor is strongly impacted by differential diffusion and partial premixing, not included in the FPI approach. This leads to a strong under-prediction of soot levels by about one order of magnitude with FPI, while ARC recovers the correct measured soot concentrations.},

abstract = {Large Eddy Simulation (LES) is progressively becoming a crucial design tool for the next generation of aeronautical combustion chambers. However, further improvements of the predictive capability of LES is required especially for predictions of pollutant formation. In general, the exact description of real fuel combustion requires to take into account thousands of unique chemical species involved in complex and highly non-linear chemical reaction mechanisms, and the direct integration of such chemistry in LES is not a viable path because of excessive computational demands and numerical stiffness. Modeling of real aeronautical transportation fuel is further complicated by the fact that kerosenes are complex blends of a large number of hydrocarbon compounds and their exact composition is very difficult to determine. In this work, we propose a new framework relying upon the Hybrid Chemistry (HyChem) approach and Analytically Reduced Chemistry (ARC) to allow a direct integration of real fuel chemistry in the compressible LES solver AVBP. The HyChem-ARC model is coupled with the Dynamically Thickened Flame LES model (DTFLES) and a Lagrangian description of the spray to investigate the turbulent two-phase flow flame in a lean direct injection combustor, fueled with Jet-A. The LES results are compared to experimental data in terms of gas velocity, temperature and species (CO2, H2O, CO, NO) mass fractions. It is found that the proposed methodology leads to very satisfying predictions of both the flow dynamics and the NOx levels. Additionally, the refined level of chemistry description enables to gain valuable insights into flame/spray interactions as well as on the NOx formation mechanism in such complex flame configurations. To improve further the results, a more detailed experimental characterization of the liquid fuel injection should be provided.},

abstract = {Downsized spark ignition engines coupled with a direct injection strategy are more and more attractive for car manufacturers in order to reduce pollutant emissions and increase efficiency. However, the combustion process may be affected by local heterogeneities caused by the interaction between the spray and
turbulence. The aim for car manufacturers of such engine strategy is to create, for mid-to-high speeds and
mid-up-high loads, a mixture which is as homogeneous as possible. However, although injection occurs during
the intake phase, which favors homogeneous mixing, local heterogeneities of the equivalence ratio are still
observed at the ignition time. The analysis of the mixture preparation is difficult to perform experimentally
because of limited optical accesses. In this context, numerical simulation, and in particular Large Eddy Simulation (LES) are complementary tools for the understanding and analysis of unsteady phenomena. The paper
presents the LES study of the impact of direct injection on the mixture preparation and combustion in a spark
ignition engine. Numerical simulations are validated by comparing LES results with experimental data previously obtained at IFPEN. Two main analyses are performed. The first one focuses on the fuel mixing and the
second one concerns the effect of the liquid phase on the combustion process. To highlight these phenomena,
simulations with and without liquid injection are performed and compared.},

The model, named PAMELA, expresses the drop size Probability Density Function of the spray in the form of a Rosin–Rammler distribution whose parameters depend on flow conditions. A mechanism of liquid fragmentation is proposed where a Rayleigh–Taylor instability develops in the transverse direction. The wavelength of this instability (i) is assumed to be proportional to the Sauter Mean Diameter of the spray, and (ii) scales with a Weber number based on the atomizing edge thickness, providing a first link between flow conditions and the Rosin–Rammler parameters. The second link is found by introducing a second Weber number based on the thickness of the boundary layer developing on the prefilmer. A first comparison with academic experiments shows that the model assumptions are valid and allows to calibrate the model constants. PAMELA is then implemented in a LES solver to perform the numerical simulation of an academic airblast atomizer. The obtained drop size distribution and spatial structure of the spray are in good agreement with measurements, demonstrating the validity of the proposed approach in the context of LES, and that the proposed PAMELA model may now be used to describe the liquid spray in LES of industrial nozzles.}}

abstract = {In industrial refinery furnaces, the efficiency of thermal transfer to heat crude oil before distillation is often altered by coke deposition inside the fuel pipes. This leads to increased production and maintenance costs, and requires better understanding and control. Crude oil fouling is a chemical reaction that is, at first order, thermally controlled. In such large furnaces, the predominant heat transfer process is thermal radiation by the hot combustion products, which directly heats the pipes. As radiation fluxes depend on temperature differences, the pipe surface temperature also plays an important role and needs to be predicted with sufficient accuracy. This pipe surface temperature results from the energy balance between thermal radiation, convective heat transfer, and conduction in the solid material of the pipe, meaning that the thermal behavior of the whole system is a coupled radiation–convection–conduction problem. In this work, this coupled problem is solved in a cylindrical furnace, in which the crude oil flowing in vertical pipes is heated. The thermal radiation of combustion gases is modeled using the discrete ordinate method (DOM) with accurate spectral models and is coupled to heat conduction in the pipe to predict its wall temperature. The flame is described with a complex chemistry combustion model. An energy balance confirms that heat transfers are effectively dominated by thermal radiation. Good agreement with available measurements of the radiative heat flux on a real furnace shows that the proposed approach predicts the correct heat transfers to the pipe. This allows an accurate prediction of the temperature field on the pipe surface, which is a key parameter for liquid fouling inside the pipe. This shows that the thermal problem in furnaces can be handled with relatively simple models with good accuracy},

abstract = {This article explores the possibility of analyzing combustion instabilities in liquid rocket engines by making use of Large Eddy Simulations (LES). Calculations are carried out for a complete small-scale rocket engine, including the injection manifold thrust chamber and nozzle outlet. The engine comprises 42 coaxial injectors feeding the combustion chamber with gaseous hydrogen and liquid oxygen and it operates at supercritical pressures with a maximum thermal power of 80 MW. The objective of the study is to predict the occurrence of transverse high-frequency combustion instabilities by comparing two operating points featuring different levels of acoustic activity. The LES compares favorably with the experiment for the stable load point and exhibits a nonlinearly unstable transverse mode for the experimentally unstable operating condition. A detailed analysis of the instability retrieves the experimental data in terms of spectral features. It is also found that modifications of the flame structures and of the global combustion region configuration have similarities with those observed in recent model scale experiments. It is shown that the overall acoustic activity mainly results from the combination of one transverse and one radial mode of the chamber, which are also strongly coupled with the oxidizer injectors.

abstract = { The design and optimization of liquid-fuel rocket engines is a major scientific and technological challenge. One particularly critical issue is the heating of solid parts that are subjected to extremely high heat fluxes when exposed to the flame. This in turn changes the injector lip temperature, leading to possibly different flame behaviors and a fully coupled system. As the cham- ber pressure is usually much larger than the critical pressure of the mixture, supercritical flow behaviors add even more complexity to the thermal prob- lem. When simulating such phenomena, these thermodynamic conditions raise both modeling and numerical specific issues. In this paper, both sub- critical and supercritical Hydrogen/Oxygen one-dimensional, laminar flames interacting with solid walls are studied by use of conjugate heat transfer simulations, allowing to evaluate the wall heat flux and temperature, their impact on the flame as well as their sensitivity to high pressure and real gas thermodynamics up to 100 bar where real gas effects are important. At low pressure, results are found in good agreement with previous studies in terms of wall heat flux and quenching distance, and the wall stays close to isothermal. On the contrary, due to important changes of the fluid trans- port properties and the flame characteristics, the wall experiences significant heating at high pressure condition and the flame behavior is modified. },

The sensitivity of the simulation to the injection diameter, the energy input to the mixture, and the time of fueling were assessed. The flame structure following ignition was shown to be complex and time dependent. The flame propagation through the chamber was analyzed using a formulation for the velocity of isosurfaces of temperature, showing that it was dominated by the gas velocity. In particular, both the swirling flow issuing from the injectors and the dilatation effect that modifies the gas flow aid the flame propagation through the chamber},

abstract = {This article reviews the modeling challenges for performing Large Eddy Simulations
of aero-nautical combustion chambers. Since the kerosene is injected in a liquid
phase into the combustion chamber, the description of the atomization is of primary
importance. The article first discusses the numerous numerical challenges encountered
during this process, which leads to the formation of small droplets that constitute
a spray. The existing numerical and modeling methods to describe a spray of kerosene
droplets are then presented. The article then focuses on the description of the complex
combustion kinetics. Hundreds of species and thousands of reactions have to be
considered to predict ignition, flame stabilization and pollutant emissions. Due to lengthy
computational times, detailed chemical schemes are too large to be directly used
in CFD. This article then presents the major existing chemical reduction strategies.
Significant interactions of the reactions layers with the flow vortices occur at the subgrid
scale. The question of turbulent combustion modeling is therefore discussed in an
LES context. Finally, the prediction of soot and NOx formation is presented. The review
is illustrated by several examples representative of practical situations encountered in
aeronautical combustors.},

abstract = {The ignition transient is a critical fundamental phase in combustion systems that has strong practical implications. While this phenomenon has been extensively studied on single injector configurations, the burner-to-burner propagation of a full annular combustor is rarely investigated, due to the size and complexity of the geometry involved. To this purpose, an annular experimental setup has been developed at EM2C, featuring sixteen swirl injectors and quartz tubes providing a direct optical access to the flame. Ignition has been investigated systematically on this device, thus providing a large experimental database. In this work, this experiment is computed in the Large Eddy Simulation (LES) framework by carrying out massively parallel computations. This constitutes a unique comparison between experiments and calculations of a critical process for gas turbines. The ability of turbulent combustion models to properly retrieve the flame structure and propagation at the largest scales is not yet fully assessed and is investigated in this paper by comparing two conceptually different combustion modeling approaches, namely the filtered tabulated chemistry (F-TACLES) and the flame thickening with reduced chemistry (TFLES). Qualitative and quantitative comparisons between both simulations and experiment show an overall excellent agreement.},

abstract = {To comply with stringent pollutant emission regulation, low-emission aeronautical gas turbines rely on lean premixed combustion. Such technology raises the issue of ensuring a reliable ignition since the combustor operates closer to blow-off. Ignition is however known as a stochastic phenomenon, associated to various sources of system variability. These variabilities and their impact on the success or failure of ignition are still not fully understood. In this paper, Large Eddy Simulation (LES) of laser ignition sequences in an academic swirled turbulent partially premixed burner are performed to obtain statistical information at three selected ignition locations representative of the various ignition scenarios observed. The velocity and mixing fields are first validated against measurements to eliminate uncertainty associated with the non-reacting flow. LES is then shown to recover the ignition statistical behavior and probability for the selected ignition locations. Moreover, LES analysis allows to identify the various mechanisms that drive ignition failure or success. Statistics of flame displacement speed are used to demonstrate the effect of curvature and stretch in regions of intense turbulence and the impact of partial premixing on the ignition process.},

abstract = {This article describes a numerical investigation that explores the dynamics of multiple cryogenic jet flames interacting with high frequency transverse acoustic modes. This research is motivated by the numerous issues associated with high-frequency instabilities in liquid rocket engines. Large eddy simulations are carried out in a complex flow configuration which is turbulent, reactive, transcritical and in the absence or presence of a large-amplitude acoustic motion. The geometry is that of a model scale experimental configuration. Results obtained by exploiting high end computational resources demonstrate the feasibility of such calculations, provide insight in the coupling process, exhibit features which are found in experiments and complement the experimental data. Depending on the acoustic environment (dominated by velocity or pressure oscillations), selective responses of the cryogenic jets and flames can be observed and analyzed. It is found that the flames are more compact when they are made to interact with the transverse acoustic motion and that the dense core length is notably reduced. In the span-wise direction, the flames and dense cores are flattened, a feature which is also found in experiments. The unsteady motion observed experimentally is well retrieved numerically. The simulations highlight the mechanisms that can feed energy in the transverse mode and suggest possible descriptions of the instability driving process. The light methane jet is shaken by the acoustic motion and impacts the dense oxygen stream alternatively on its top and bottom sides. The unsteady heat release rate and the corresponding acoustic Rayleigh term produced by the flames prove to be different according to the flame position regarding the acoustic environment.},

abstract = {A methodology is presented which allows to predict soot levels produced in simple, one-dimensional laminar flames. The method is applied to the calculation of a set of well documented ethylene/air counterflow diffusion flames, using a detailed chemical mechanism (Davis et al., 1999 [1]) and a semi-empirical, two-equation soot model from Leung and Lindstedt (1991) [2]. Modifications of the original soot model are made in order to retrieve the experimental measurements of Hwang and Chung (2001) [3]. To account for radiative heat losses, a second series of fully coupled gas/soot/radiation simulations of the counterflow flames is performed. This allows to assess the effect of soot and gas radiation on soot formation and on the flame structure.},

abstract = {This paper describes a numerical study based on Large Eddy Simulation (LES) of theFLow induced by a supersonic jet impinging on a flat plate in a stable regime. This flow involves very high velocities, shocks and intense shear layers. Performing LES on such flows remains a challenge because of the shock discontinuities. Here, LES is performed with an explicit third-order compressible solver using a unstructured mesh, a centered scheme, and the Smagorinsky model. Three levels of mesh refinement (from 7 to 22 million cells) are compared in terms of instantaneous and averaged flow fields (shock and recirculation zone positions), averaged flow velocity and pressure fields, wall pressure, RMS pressure fields, and spectral content using one and two point analyses. The effects of numerical dissipation and turbulent viscosity are compared on the three grids and shown to be well controlled. The comparison of LES with experimental data of Henderson et al. shows that the finest grid (a 22 M cell mesh) ensures grid- independent results.

abstract = {This paper presents the numerical computation of a turbulent jet of nitrogen into nitrogen under supercritical pressure. The large-eddy simulation framework for turbulence modeling is used and real-gas effects are accounted for through a cubic equation of state and appropriate viscosity and conductivity coef␣cients. The purpose of this paper is to evaluate how low-pressure large-eddy simulation equations coupled with real-gas thermodynamics and transport compare with experiments. Although this approach does not take into account the impact of high density gradients and nonlinear thermodynamics on turbulence modeling, the results show reasonable agreement with available experimental data and reveal the importance of numerics for such computations. The simulations indicate a limited influence of the density ratio and the thermodynamic conditions on the jets spreading rate and pseudosimilarity behavior.

abstract = {In the last decade, the urge to reduce the impact of aviation on climate change has led engine manufacturers
to move to lean-burning conditions and to consider alternative fuels such as Sustainable Aviation Fuels (SAFs).
Those changes have a significant impact on the Lean blow-out (LBO) limit which is a critical safety aspect of the
engine operability. Complementary to experiments, working on the capability to numerically predict LBO events
is essential for further understanding and support to design. In the present work, the LES AVBP solver is used to
predict the LBO limit of the SSB spray burner operated at DLR. It shows that LBO is very sensitive to the thermal
state of the burner and that accurate wall thermal conditions are therefore required for a good LBO prediction.},

abstract = {Partially magnetized E×B discharges are highly coupled systems and subject to many plasma
instabilities. In particular, the important electron drift velocity with respect to unmagnetized
ions can lead to the growth and development of the Electron Drift Instability (EDI). The EDI
has been the focus of extensive experimental, theoretical and numerical studies over the last
two decades as it is suspected to play a role in the anomalous transport of electrons across
the magnetic barrier. Despite significant progress, numerical investigations, mostly based on
Particle-In-Cell modeling, have been mainly limited to 2D dimensional geometry due to the
prohibitive computational cost of fully kinetic simulations. In this paper, we present the last
developments of a 3D Particle-In-Cell study of a simplified Hall thruster allowing us to explore
further the 3D structure of the EDI.},

The comparison with the reference skeletal scheme presents some differences on the transition from auto-ignition to flame propagation but a reasonable agreement is observed for the overall ignition sequence and the CPU cost is largely reduced. Then, an exponential integration of
chemistry and an automatic sub-cycling procedure are presented. These methods enable further CPU-cost reduction while keeping a correct precision on the results. Finally, the combination of these methods is applied to a three-dimensional DNS of turbulent kerosene ignition.},

abstract = {t is well-known that electric fields are very efficient tools to actively controlling the multiple aspects of combustion. Laboratory experiments have shown that the appropriate use of an external electric field can extinguish a flame, reduce its soot, CO, and nitrogen oxide emissions, and vary its lift-off height. The numerical simulation of these phenomena has remained elusive to the scientific community because of the physical and numerical complexity of the physical phenomena that regulate this interaction. In this study, we present new calculations performed using a multi-component compressible Navier--Stokes solver, called HTR solver (Di Renzo et al., Comp. Phys. Comm. 2020), which has been modified in order to include the effects of the ion transport due to electric fields. A peculiar aspect of this solver is its implementation in the task-based environment provided by the Legion runtime system, which makes the solver highly scalable and portable on machines with heterogeneous architectures. The presented calculation will focus on the modifications induced by an external electric field on a diffusion flame of methane and air developing in a turbulent temporal shear layer.},

While most of the papers are focused on simplex atomiser with only one fuel passage, we propose to account for specific industrial configurations based on duplex atomiser where both the primary and the secondary passages operate. For the second passage, the fuel spray angle is wider, leading to spray / wall interactions and airblast atomization.
The computation domain consists in the experimental mock-up without the fuel atomizer part. The liquid-injection boundary condition is applied through the phenomenological FIM-UR model, which prescribes droplet velocities and diameter distribution at the atomizer tip based on both the atomizer characteristics and the liquid mass flow rate. No specific models are used for spray / wall interaction, and droplets are assumed to slip on the walls. The numerical results are compared with the experimental database for Jet-A1 fuel, built through Phase Doppler Anemometry instrumentation, allowing access to local information regarding the droplets velocity components.
Three LES are performed for pressure loss ranging from 1 to 3%, covering an important part of the engine operating conditions, from high altitude relight to cruise operating point. Mean and fluctuating velocity profiles show a relatively good agreement with measurements, for all the operating points. It confirms that the spray/wall interactions, airblast and secondary breakup models may be neglected as a first approximation for configurations where only a relatively small amount of fuel impacts the wall.},

The neural network solves the Poisson equation, necessary to update the velocity field provided by the resolution of the advection equation. Several U-Net architectures, parametrized by their number of downscaled branches (DBs) and receptive field (RF), are evaluated on the Von Karman oscillations generated by a 2D cylinder at low Reynolds numbers. Results are compared with other standard Poisson and CFD solvers, revealing that the Von Karman oscillations can be reproduced accurately using the CNN-based solver with fast inference time. To further analyze the error, Dynamic Mode Decomposition (DMD) is applied on the solutions, revealing the key effects of both DBs and RF on the modes accuracy, shedding new light on the behavior and limitations of CNN when interacting with CFD solvers.},

abstract = {There has been a tremendous increase in the production of ethylene over the past couple of decades and
this trend is expected to continue in the foreseeable future as well. Steam cracking- the principal process
used for the production of ethylene has gained increasing interest, both at a fundamental as well as at a
systems level, with the ultimate objective of making ethylene production energy-efficient and lesser polluting
(https://cerfacs.fr/improof/).
Numerical studies published in the past used Reynolds Averaged Navier-Stokes (RANS) equations
coupled with the Radiative Transfer Equation (RTE) to solve for the mean flow field. However, for gaining
deeper insights about the combustion occurring inside the furnace, unsteady flow features need to be
captured using accurate and proven numerical techniques such as Large Eddy Simulation (LES). The
challenges associated with LES of steam cracking furnaces include the presence of large spatial and
temporal scale separation and the concomitant high computational cost, modeling accurate and sufficiently
detailed chemistry to predict combustion and incorporating radiative heat transfer effects. In this study, the
LES of a steam cracking furnace is carried out for the first time, by addressing the first two of the abovementioned
challenges using novel numerical methods and chemistry reduction techniques.
Although LES solvers based on explicit time integration schemes, such as AVBP (www.cerfacs.fr/avbp7x),
exhibit excellent numerical resolution and accuracy, they are limited in the maximum allowable time step
that can be used, due to numerical stability requirements. This limitation is aggravated even further in the
case of simulations of furnaces due to small time steps and large flow-through times. In this study, this issue
of stiffness is addressed using a novel acceleration technique based on local time-stepping coupled with
overset grid methodology. The acceleration technique is validated on multiple test cases and shown to incur
a minimum loss in simulation accuracy. The technique is used in the current simulation and speedup by a
factor of 4 was observed.
Accurate prediction of temperature, heat release and pollutants inside the furnace requires accurate
chemistry at a reasonable computational cost. In this study, a recent and detailed chemical mechanism for
methane combustion is analytically reduced using the classical DRGEP method and QSS approximation
tool ARCANE (https://cerfacs.fr/chemistry/en/arcane/). The reduced mechanism is validated with the
detailed one and found to reproduce all the relevant chemical features of the detailed scheme accurately.
In this paper, the LES simulation results are compared with available measurements of temperature. This
study emphasizes the need for the engineering community to embrace LES as a furnace and burner design
tool by demonstrating its application on a real steam cracking furnace.},

abstract = {The Poisson equation is present in very different domains of physics and engineering. In most cases, this equation can not be solved directly and iterative solvers are used. For many solvers, this step is computationally intensive. In this study, an alternative resolution method based on neural networks is evaluated for incompressible flows. A fluid solver coupled with a Convolutional Neural Network is developed and trained on random cases with constant density to predict the pressure field. Its performance is tested in a plume configuration, with different buoyancy forces, parametrized by the Richardson number. The neural network is compared to a traditional Jacobi solver. The performance improvement is considerable, although the accuracy of the network is found to depend on the flow operating point: low errors are obtained at low Richardson numbers, whereas the fluid solver becomes unstable with large errors for large Richardson number. Finally, a hybrid strategy is propos
ed in order to benefit from the calculation acceleration while ensuring a user-defined accuracy level. In particular, this hybrid CFD-NN strategy, by maintaining the desired accuracy whatever the flow condition, makes the code stable and reliable even at large Richardson numbers for which the network was not trained for. This study demonstrates the capability of the hybrid approach to tackle new flow physics, unseen during the network training.},

abstract = {Combustion is today, and by far, the main source of energy and the basis of our modern way
of life. Replacing combustion with renewable energy (solar or wind) is still out of reach unless
drastically reducing our consumption or increasing nuclear energy. It has however two major
drawbacks: the use of fossil fuel, which by definition will come to an end, and the emission of
pollutants which are toxic for human health and contribute to the climate change. It is therefore
critical to develop combustion processes and systems that reduce or even suppress these problems.
Combustion is the combination of chemistry and fluid mechanics, and therefore contains many
non-linearities. The presentation will review these linearities and their interactions. An overview of
the main resolution techniques used today will be given, as well as of the current research on new
numerical approaches. Examples of applications will be finally given to illustrate the state-of-the-art
of numerical combustion.},

abstract = {Large eddy simulation (LES) of large size flames and hot gas
plumes, as observed in furnaces or open fires, are very rare as
they pose multiple challenges due to the presence of a wide
spectrum of scales (in length and time, with a ratio of up to 10E4
in length and 10E8 in time), as well as multiple physics (chemistry,
compressible turbulence, buoyancy and multiple heat transfer
modes) and their complex interactions. LES solvers based on
explicit time integration methods are known for their superior
accuracy and resolution properties, but suffer from constraints
on the maximum allowable time step imposed by the smallest
computational cell, thereby impeding their efficient application
to such multiscale problems. Thanks to an original and efficient
multiscale computational strategy, a turbulent diffusion flame of
a 15m high steam cracking furnace has been simulated for the
first time with LES using the code AVBP, an explicit, compressible
reactive flow solver. Analytically reduced chemistry (ARC), a novel
and proven technique used to reduce the number of species
and reactions from a detailed mechanism while still preserving
the global kinetic properties accurately, has been used. An ARC
mechanism optimized for methane combustion was derived and
used in the study and NOx and CO emissions at the furnace
exit have been predicted. In this work, a detailed analysis of the
structure and dynamics of the obtained numerical flame and
plume is proposed, giving new insight on turbulent combustion
features at large scale and its implications for pollutant emissions.},

high pressure, high strain rate flow. To do so, an Analytically Reduced Chemistry (ARC)
is specifically derived for this test case. The ARC is validated by comparison with its
parent skeletal mechanism on a series of laminar flames at conditions representative
of the target LES configuration. To address the issue of numerical stiffness of oxycombustion, an original approach for time integration of chemistry is proposed, allowing to run the simulation at the CFL timestep. It is demonstrated on 1D and 2D laminar cases that the flame structure is well preserved, and that stability is ensured by decreasing CPU cost at the same time. Finally, the ARC for methane oxycombustion is combined with the proposed time integration method to compute the experimental combustion chamber. Results show a purely non-premixed turbulent flame, with a complex chemical structure. It is found that the proposed time integration method for chemistry allows a substantial gain of computational cost.},

abstract = {Electric propulsion can reach higher exhaust velocities compared to chemical systems and
thus result in lower propellant mass requirements. Among the different electric propulsion
systems, Hall effect thrusters are used for spatial propulsion since the 1970s. However inside
a Hall thruster, complex physical phenomena such as erosion or electron anomalous transport
which may lower thruster efficiency and lifetime, are not yet fully understood. Thanks
to high performance computing, numerical simulations are now considered for understanding
the plasma behavior. With the renewed interest for such electric propulsion to supply small
satellites, numerical solvers able to predict accurately the real thruster efficiency have become
crucial for industry.
This paper presents the approach used and first validation tests of such a solver. The AVIP
code solves plasma equations in complex industrial geometries using an unstructured parallelefficient
3D fluid methodology. AVIP also includes a Particle-In-Cell (PIC) solver used as a
reference for validation. While full 3D PIC simulations of a Hall thruster still require unaffordable
computational time, fluid models provide in a reasonable time 3D results on the plasma
behavior inside the discharge channel. In this category, standard drift-diffusion models [1–3]
are fast and robust but at the cost of strong hypotheses and simplifications. In particular such
models do not describe explicitly the sheath formation in the vicinity of walls and often use analytical
models instead. They are limited to simple configurations and only provide a first insight
into plasma complex phenomena. The present approach includes a more detailed two-fluid
plasma model without drift-diffusion approximation. After the description of the formulation
and main features of the solver, the paper focuses on wall boundary conditions which are
crucial for the formation of sheaths. It is demonstrated in particular that a vacuum boundary
condition is not adapted to fit PIC results. A boundary condition based on wall thermal fluxes
is more realistic. The mesh resolution is also found to be critical. The simulation methodology
is finally applied to a 2D simulation of a typical Hall effect thruster in order to observe the
plasma properties inside the discharge chamber.},

Also important are the use of high-order time and space discretization methods, and sufficiently small time steps to ensure accurate temporal evolution of the reacting flowfield. Strict adherence to the many criteria put forth leads to heavy computational demands. ; The engineer interested in industrially useful answers is left to wonder how strictly the academic criteria for valid LES must be followed to get answers su
fficient to guide engineering design. In this paper we will attempt to address this issue, drawing from academic literature, published industrial work and our own experience.},

abstract = {The numerical prediction of pollutant emissions or bio-fuel flame structure in industrial
combustors such as aeronautical engines, ground-based gas turbines or furnaces, requires an
accurate description of combustion chemistry. Such precision may be achieved with detailed
chemical kinetics mechanisms which have been developed in order to accurately capture all
the details of the combustion process over a wide range of thermodynamic conditions.
However, these mechanisms involve many species and reactions, making them too
expensive for numerical simulation of 3D industrial cases. One solution to this problem is
to reduce the complexity by targeting a specific operating range of temperature, pressure,
and equivalence ratio, representative of the real case, as well as specific species that are of
importance if one wants to account for ??# or soot production for example.
Such reduced mechanisms have been successfully derived using the multi-stage reduction
code YARC [1] with the following procedure. First, Direct Relation Graph with Error
Propagation (DRGEP) [2] is applied on species and reactions with specified species as
targets (typically fuel, oxidizer, and pollutants of interest), followed by chemical lumping,
resulting in a skeletal mechanism accounting for the relevant species and reactions only.
Finally, a timescale analysis along with DRGEP is used to identify species that can be set in
Quasi-Steady State (QSS) in order to further speed up the calculation.
In collaboration with Pr. P. Pepiot, a new automatic reduction tool called ARCANE has been
developed to make it more efficient, more flexible and easier to use. ARCANE relies on the
Cantera chemistry solver [3] and is written in Python language. ARCANE tool has been
benchmarked against YARC on canonical cases validating it.
This talk will first present the main features of ARCANE. Then, an example of reduction
for methane-air combustion will be presented. Analytically Reduced Chemistries (ARC) are
first compared to detailed mechanisms on 0D reactor and 1D flame configurations in the
target operating range, and confirm that the error induced by the reduction is small enough
to correctly capture important features such as intermediate species profiles, ignition delay
time and laminar flame speed. Finally, several strategies to model complex fuels such as
kerosene in the scope of Large Eddy Simulation (LES) will be presented: n-decane (?%&?(()
as a mono-component surrogate of kerosene, the HyChem mono-component model [4,5] but
accounting for the full composition of kerosene, and finally the multi-component approach.
This latter is necessary to study the impact of alternative fuel addition to Jet A1 on the
operability of an aeronautical combustor, which is one main objective of the H2020
JETSCREEN European project.},

aeronautical combustion chambers. However, further improvements of the capability of LES is required
for predicting pollutant emissions. Indeed, the detailed description of fuel pyrolysis and oxidation requires
to take into account hundreds of chemical species involved in the complex non-linear reaction process.
The direct integration of such detailed chemistry in LES is not a viable path, because of excessive compu-
tational demands and numerical stiffness. Modeling real transportation fuel is further complicated by the
fact that kerosenes are complex blends of a large number of hydrocarbon compounds; the exact composi-
tion of which is very difficult to determine. In this work, the real-fuel combustion chemistry is described
by the Hybrid Chemistry (HyChem) approach; and an LES-compliant Analytically Reduced Chemistry
(ARC) is used to allow a direct integration of the fuel chemistry in the LES solver. The ARC mecha-
nism is coupled with the Dynamically Thickened Flame LES model (DTFLES) and a Lagrangian spray
description to investigate the turbulent two-phase flow flame of a lean direct injection combustor, fueled
with Jet-A. The LES results are compared to experimental data in terms of gas velocity, temperature and
major species (CO2, H2O, CO, NO) mass fractions. It is found that the proposed methodology accurately
predicts both the flow dynamics and pollutant formation, and presents therefore a great potential to study
complex flame configurations burning real jet fuels},

abstract = {Reacting numerical simulations today are often based on either fitted global reaction schemes, comprised of a few empirical reactions, or pre-tabulated laminar
flame solutions computed with detailed chemistry. Although both methods can accurately predict global quantities such as laminar FKame speed and burnt gas composition, they have significant limitations. In particular, neither are able to directly and adequately describe the complexity of pollutant chemistry. In the
context of reducing harmful emissions, however, including these needed additional kinetic details in combustion simulations is becoming essential. Direct integration of detailed chemistry in accurate turbulent combustion models is not a viable option in the foreseeable future. In this context, Analytically Reduced Chemistry (ARC) represents an attractive compromise between accuracy and efficiency, and is already employed in relatively complex Direct Numerical Simulations (DNS) and
Large Eddy Simulations (LES). ARCs are knowledge-based compact mechanisms retaining only the most relevant kinetic information as extracted directly, and without fitting, from detailed chemical models using specialized reduction techniques. YARC is a multi-step automated reduction tool, composed of a selected subset of very efficient reduction techniques (DRGEP, Chemical Lumping, and QSS species identification), that generates ARCs from detailed mechanisms with minimum input and knowledge from the user. This paper presents a review of recently YARC-derived ARCs for fuels ranging from methane to Jet-A aviation kerosene, along with validations in canonical test cases and, whenever possible, references of use in 3D DNS and LES.},

The objective is to evaluate the flame propagation speed in the case where droplets evaporate inside the reaction zone with possibly non-zero relative velocity. Numerical simulations consist in one-dimensional resolved simulations coupled to Discrete Particle Simulation for the dispersed phase.
A two-step n-heptane/air chemical mechanisms is used. The effects of initial droplet diameter, overall equivalence ratio phi-tot and relative velocity between gaseous and liquid phase are studied. For lean premixed cases, it is found that the laminar
ame speed decreases with large initial droplet diameter and high relative velocity. On the contrary, rich premixed cases show a range of diameter for which the
ame speed is enhanced compared to the purely gaseous flame.},

abstract = {In order to guarantee good re-ignition capacities in case of engine failure during flight, it is of
prime interest for engine manufacturers to understand the physics of ignition from the spark discharge
to the full burner lightning. During the ignition process, a spark plug delivers a very short and powerful
electrical discharge to the mixture. A plasma is first created before combustion reactions initiate, resulting
in a small flame kernel [1]. The present work focuses on this still misunderstood first instants of ignition, i.e.
from the sparking to the flame kernel formation. 3D Direct Numerical Simulations of propane-air ignition
sequences induced by an electric discharge are performed with the AVBP solver on a simple anode-cathode
set-up. An Analytically Reduced Chemistry (ARC) including 38 species and 366 irreversible reactions has
been developed and used to describe the coupled combustion and plasma kinetics. The e ect of plasma
chemistry on the temperature field is found to be non-negligible up to a few microseconds after the spark
due to endothermic dissociation and ionization reactions. However its impact on the subsequent flame kernel
development appears to be weak in the studied configuration},

abstract = {Partly due to stringent restrictions on pollutant emissions, aeronautical engine manufacturers need to design engines working on more tricky operating points such as close to the lean extinction limit. Such new concepts of course constrain engine designers to understand better the
physics behind some phenomena directly impacted. For instance, lean combustion is detrimental to the crucial ignition and re-ignition capabilities of the engine in high altitude as ignition failure is more likely to happen close to the lean extinction limit. A deeper understanding of highly stochastic
spray ignition and extinction phenomena is then required. In this work, a joint experimental and numerical investigation of the academic swirled-confined version of the KIAI spray burner is carried out. Both experimental diagnostics, such as Phase Doppler Anemometry (PDA), high-speed
PIV and toluene-PLIF and Large Eddy Simulations coupled to Discrete Particle Simulations are used to first characterize the two-phase
flow dynamics. A good agreement is found in non-reactive and reactive conditions. Then, an experimental ignition probability map of the chamber is provided showing the strong influence of cold flow local properties such as turbulent kinetic energy or equivalence ratio. Finally, ignition sequences started at different positions of the chamber are studied both experimentally and numerically in details. The same mechanisms leading to successful
or failed ignition events are identified.},

abstract = {The challenges found on the route to developing quantitative wildfire behavior models are two-fold. There is the modeling challenge associated with providing accurate representations of the complex multi-physics processes that govern wildfire dynamics. There is also the data challenge associated with providing accurate estimates of the in put data required by the models (e.g. biomass fuel moisture, near-surface meteorology). For this purpose, the uncertainty in regional-scale wildfire behavior modeling must be quantified and reduced. An ensemble-based data assimilation algorithm (i.e. ensemble Kalman filter –EnKF) is implemented for the sequential estimation of the input parameters of a fire spread model carried out when fire front observations are available.
This algorithm requires the stochastic estimation of the covariances between the model input parameters and the model outputs (generally through a Monte Carlo method). The difficulty with the crude Monte Carlo method is due to the convergence, for instance the approximation of quantile could be time-consuming due to possible model non-linearity. Wediscuss the use of techniques like surrogate modeling (Polynomial Chaos–PC) to build numerical representations of the wildfire behavior model,which are used in the framework of the EnKF algorithm to accuratelyestimate model error statistics.
The performance of the hybrid PC-EnKF strategy is illustrated on academic tests and in the context of wildfire spread forecasting.

This configuration features 42 coaxial injectors fed with liquid oxygen and gaseous hydrogen. For a given set of injection conditions the combustor exhibits strong transverse thermo-acoustic oscillations that are retrieved by the numerical simulation. The spatial structure of the two main modes observed in the LES is investigated through 3D Fourier analysis during the limit cycle. They are respectively associated with the first transverse and first radial resonant acoustic modes of the combustion chamber. The contributions of each individual flame to the unsteady heat release rate and the Rayleigh index are reconstructed for each mode. These contributions are in both cases low in the vicinity of velocity anti-nodes and high near pressure anti-nodes. Moreover it is noticed that these pressure fluctuations lead to large velocity oscillations in the hydrogen stream. From these observations, a driving mechanism for the flame response is proposed and values for the gain and phase of the associated flame transfer function are evaluated from the LES.}}

abstract = {Combustion in cryogenic engines is a complex phenomenon, involving either liquid or supercritical fluids, strong and fast oxidation chemistry, and
high turbulence intensity. To understand and control the physics at play in such combustor, the Large Eddy Simulation (LES) approach is an efficient and reliable numerical tool. In addition, a particularly critical issue in rocket engine is wall
heat transfer, which requires efficient cooling. In the expander-type engine cycle, the cooling uses the extracted energy to drive the turbo-pumps. This requires an accurate prediction of wall heat flux. In the present work, the LES of the
CONFORTH model rocket engine experimentally studied in the framework of a ONERA-CNES project [25], is performed. The CONFORTH configuration is a water-cooled combustor, fed with five coaxial elements. One main goal of the
experiment was to study the aerothermal behaviour of the combustion chamber, equipped therefore with numerous thermocouples along the walls.
The chosen operation point for the present simulation corresponds to subcritical conditions, which means that oxygen is injected in its liquid state. The simulations are performed with the code AVBP of CERFACS and IFPEN [9], using a 12-steps chemical scheme for the H2=O2 flame and a liquid spray solver. The boundary layer is modeled through dynamic and thermal wall laws. The LES is conducted with imposed wall temperature, known from measurement, to predict the wall heat flux. Simulation results give detailed information on the flow and flame structures, and on their interaction with the walls. The accuracy of dynamic and thermal wall laws, combined with the sub-grid scale turbulence model, is evaluated and discussed to propose new paths for improvement.

abstract = {Large Eddy Simulation (LES) is now recognized as an efficient numerical tool to predict gaseous combustion in industrial burners, and a number of examples of applications can be found in the literature. In these examples, the accuracy and the predictive capacity of LES are clearly demonstrated, even for unsteady phenomena. However most industrial burners are fed with liquid fuel and require the description of droplets dispersion, evaporation and burning. The presence of liquid fuel strongly modifies the fuel vapor distribution in the chamber, leading to different flame ignition and stabilisation processes, as well as different flame structures. Extending the LES technique to two-phase reacting flow is therefore crucial to capture and predict the behavior of such burners. This has been done in the code AVBP, coupling an eulerian solver for the liquid spray with a LES solver for the gas flow. This approach allows to work on unstructured grids and therefore to calculate the flow in complex geometries. In the present paper, the main steps of the extension of LES to two-phase flow are described and an example of validation is given. Then the solver is applied to the Vesta combustor of Turbomeca, composed of 18 main burners ignited by two pilot flames. This illustrates the capacity of LES to compute complex two-phase reacting flows in transient regimes. To demonstrate LES efficiency, some results will be shown for a calculation done on the IBM supercomputer BlueGene/L - cited by TOP500 as the world's fastest machine - where the use of 2048 parallel processors has enabled to start computing on the full combustor domain (i.e. 18 main injectors + 2 pilot flames).},

abstract = {This paper describes a single component liquid film evaporation model. Based on direct numerical simulation (DNS) results of liquid film evaporation in a turbulent channel, new mass, momentum and energy wall laws have been developed in order to take into account the strong gradients of gas density and viscosity near the liquid film, and the gas boundary-layer blowing due to the film evaporation. The liquid film model uses an integral method with a third order polynomial to compute the heat flux inside the liquid film. Moreover, liquid film thermal boundary layer during the transient heating stage is also taken into account. The wall laws and film evaporation model have been implemented in the Reynolds Average Navier-Stokes (RANS) code IFP-C3D. The comparisons of the RANS results with the DNS results are made to substantiate the model presented in this study. The shear stress and heat and mass fluxes at the liquid film interface are reproduced accurately using the new laws of the wall},

abstract = { Ground ignition and altitude re-ignition are critical issues for aeronautical gas turbine design. They are strongly influenced
by the turbulent flow structure as well as the liquid fuel spray and its atomization. Turbulent mixing, evaporation and
combustion that control the combustion process are complex unsteady phenomena coupling fluid mechanics, thermodynamics
and chemistry. To better understand unsteady combustion in industrial burners, Large Eddy Simulation (LES) is a unique
and powerful tool. Its potential has been widely demonstrated in the context of turbulent cold flows, and it has been recently
applied to turbulent combustion. Its extension to two-phase turbulent combustion is a challenge but recent results confirm that
it brings totally new insight into the physics of flames for both mean and unsteady aspects. In the present work, an Euler-Euler
formulation of the two-phase flow equations is coupled with a sub-grid scale model and a turbulent combustion model. The
obtained two-fluid model computes the conservation equations in each phase and the exchanges source terms for mass and
heat transfer between gas and liquid. Thanks to the compressible form of the gas equations, flame/acoustics interactions are
resolved. For application to complex geometries, unstructured meshes are used. With this numerical tool, turbulent two-phase
flames are simulated in an industrial gas turbine. Some of the mechanisms involved in the steady spray flame are analysed
and the partially premixed flame structure is detailed. Nevertheless, the capabilities of the LES technique for spray combustion
are not limited to the stabilised spray flame. Unsteady complex phenomena such as ignition sequences give promising
results : the unsteady behaviour of the reacting two-phase flow from the installation of a kernel to the possible propagation
and stabilisation of the flame is computed and demonstrates the LES capabilities in such unsteady complex problems.}}
