The injection of liquid fuel introduces additional complexity due to the spray-flame interaction. It is then crucial to better understand the physics behind these phenomena and to develop the capacity to predict them in an industrial context. In this work, a comprehensive joint experimental and nu- merical investigation of the academic swirled-confined version of the KIAI-Spray burner is carried out. Experimental diagnostics, such as Phase Doppler Anemometry (PDA), Planar Laser Induced Fluorescence (OH-PLIF), high-speed visualization and high-speed particle image velocimetry (HS-PIV), together with Large Eddy Simulations coupled to Discrete Particle Simulations are used to study spray flame structure and spray ignition. The analysis of the swirled-stabilized spray flame highlights the main effects of the presence of droplets on the turbulent combustion, and the complementarity and validity of the joint experiment and simulation approach. Ignition sequences are then studied. Both experiment and simulation show the same behaviors, and relate the flame kernel evolution and the possible success of ignition to the local non reacting flow properties at the sparking location, in terms of turbulence intensity and presence of droplets}, keywords = {Spray flame, Ignition, Laser diagnostics, Large Eddy Simulation}, url = {https://doi.org/10.1016/j.proci.2018.05.132}}

The Large Eddy Simulation (LES) approach is used in a wall-resolved periodic configuration. Both an adiabatic and a wall-heated simulations are performed and validated against experiment. Velocity profiles and wall temperatures were measured at the Von Karman Institute (VKI) using Stereoscopic Particle image Velocimetry (S-PIV) and Liquid Crystal Thermography (LCT) by Mayo et al. (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.}, keywords = {Heat transfer, Pressure loss, Ribbed tube}, url = {https://www.journals.elsevier.com/international-journal-of-heat-and-mass-transfer}}

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.}, keywords = {Analytically Reduced Chemistry, database , CFD applications}}

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.}, keywords = {COMBUSTION}}

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.}, keywords = {Pollutant prediction, Reduced chemistr, Large Eddy Simulation}, url = {https://www.sciencedirect.com/science/article/pii/S0010218017303504}}

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.}, keywords = {Large Eddy Simulation, Chemical kinetics, Reduced chemistry, Gas Turbines, Soot}, pdf = {https://cerfacs.fr/wp-content/uploads/2018/02/CFD_Felden-al.-CNF2018.pdf}, supplementaryMaterial = {https://www.sciencedirect.com/science/article/pii/S0010218018300099}, url = {https://doi.org/10.1016/j.combustflame.2018.01.005}}

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.

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.}}

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}, url = {http://heattransfer.asmedigitalcollection.asme.org/article.aspx?articleid=2506748}}

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.}, pdf = {https://cerfacs.fr/wp-content/uploads/2016/09/CFD_RIBER_AL11-05_0.pdf}}

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.}, url = {http://dx.doi.org/10.1016/j.proci.2014.07.008}}

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.}, url = {http://dx.doi.org/10.1016/j.proci.2014.07.040}}

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.

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.

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.

Lateral blowing impact on the stability of the flow is analysed thanks to parametric unsteady simulations by varying the flow rate over the upper surface. The results clearly show a stabilization of the flow when lateral blowing increases. Linear stability analysis on local velocity profiles enables to accurately reconstruct the mode on a selected weakly unstable case, although the frequency selection mechanism is not well captured. The same analysis is performed on a stable case and even if strong differences are noticed, linear stability do not give a conclusion as clear as the one obtained with numerical simulations. More generally, these results show a stabilization effect of the lateral blowing on corner vortex shedding and the ability of the linear stability analysis to reproduce and predict this mechanism}, keywords = {Corner vortex shedding ; solid rocket motors ; large eddy simulation ; linear stability}, pdf = {https://cerfacs.fr/wp-content/uploads/2017/06/CFD_CONFSpacePro16_Lacassagne.pdf}}

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).}, url = {http://proceedings.fyper.com/eccomascfd2006/}}

The request for more environmentally-friendly combustion systems calls now for the accurate description of chemistry, which drives pollutant emissions, but also the impact of alternative fuels or ignition capabilities. To do so, one promising approach is the so-called ARC-LES, where the chemistry is described with analytically reduced chemistry (ARC) and the turbulent combustion is modeled in the large eddy simulation (LES) framework. ARC-LES realizes an excellent compromise between accuracy and computing cost, as ARC retains the most important chemical paths and LES directly resolves the most important turbulent scales. In this chapter, the ARC concept is described in detail. After explaining the method of derivation of ARC schemes, several examples of application to turbulent flames show that ARC-LES well captures the turbulence-chemistry interaction in complex flows, and leads to very good predictions of the flame structure and emissions.}, keywords = {Chemistry, Combustion, Gas turbines, Large eddy simulation, Pollutants, Soot, Turbulence}, url = {https://doi.org/10.1016/B978-0-444-64087-1.00019-X}}
