The Chinese edition of ‘Theoretical and Numerical Combustion' (TNC) book available
2 June 2023
The TNC book is a classical textbook for engineers and researchers performing simulations of turbulent reacting flows. Its english version has been available for a long time but now, a Chinese version is also available here : TNC book is based on many results obtained first at CERFACS in the CFD team. Of course, finding typos is a little bit more difficult for most of us..
Organization of a validation workshop of CFD codes for hydrogen air flames
5 May 2023

This workshop will allow experimental data obtained by IMFT, TU Berlin and NTNU Trondheim to be distributed to all CFD groups interested in accessing high precision experimental data in order to test their software. Comparison conferences will take place, starting in november 2023. CAWH2-CLeanAviationWorskhopforH2Télécharger
IMFT and CERFACS obtain a third ERC advanced grant on H2 combustion together: SELECT-H
18 April 2023
Pr Thierry SCHULLER (Institut de Mécanique des Fluides de Toulouse, UPS) has obtained a new advanced grant from the European Research Council called SELECT-H.

CERFACS participation in the European Aviation Safey Agency (EASA) Conference
5 April 2023
The European Aviation Safety Agency (EASA) organized a conference aimed at strengthening exchanges with academia on R&I topics that could, in the near future, change the world of aviation, contribute to the development of European industry, and address new regulatory challenges for aviation authorities. The conference was held in Cologne, Germany, on 23 and 24 March and brought together PhD students and other academic representatives with EASA experts and stakeholders, government and European research institutions.Three PhD students from the GLOBC team were invited to the conference to present their findings on the impact of climate change on aviation (ICCA), an active research topic at CERFACS and one of EASA's most important concerns. Victoria Gallardo (4th year) and Suzanne Salles (2nd year) study the impact of rising temperatures on aircraft take-off, whereas Mohamed Foudad (3rd year) focuses on the impact of global warming on clear-air turbulence. Suzanne Salles received the Young Doctoral Student Award for an invitation to visit EASA to work on her topic. More details in:
Cerfacs’ envolved into TRACCS project
4 April 2023
Several Cerfacs researchers and engineers are participating in the national research program TRACCS which was officially launched last Wednesday at the CNRS headquarters in Paris.The TRACCS program (Transforming Climate Modelling for Climate Services) is one of the winners of the second wave of the call for proposals for Priority Research Programs and Equipment (PEPR) aimed at consolidating key scientific fields for the technological, economic, social or environmental transformations underway. TRACCS joins the FairCarbon and OneWater programs, selected in 2021, and IRIMa, selected in the summer of 2022, which focus respectively on the carbon cycle, the water cycle and risks.TRACCS is jointly led by CNRS and Météo-France and will receive €51 million in funding over the period 2023-2030 as part of the France 2030 investment plan. It involves other French research players, including the French Atomic Energy Commission (CEA), the Institute of Research for Development (IRD), CERFACS, Grenoble Alpes University, Sorbonne University, Paris-Saclay University and the University of Versailles Saint-Quentin-en-Yvelines.
ENSO complexity controlled by zonal shifts in the Walker circulation
4 April 2023
The El Niño Southern Oscillation is the dominant climate mode in the tropics but remains unpredictable due to strong variations in the heating zones of the tropical Pacific ocean among different El Niño events. Based on a theoretical approach, two researchers from CECI/CERFACS have shown that this diversity can be explained by the zonal (i.e. longitudinal) displacements of the background circulation of the Pacific or so-called Walker circulation. The work has been carried out within the framework of the ANR ARISE project and results have just been published in the journal Nature Geosciences ( also: results open new avenues to better understand the biases of current climate models as well as the evolution of the El Niño Southern Oscillation with climate change.
“Hydrogen week” at CERFACS and IMFT
29 March 2023
Week 13 was a strong hydrogen activity in Toulouse: - Pr Heinz Pitsch (RWTH Aachen) gave a talk on the fundamentals of hydrogen combustion on the 28th with more than 100 attendants - Dr Andrea Aniello presented his PhD on the 29th on: "Experimental and numerical assessment of H2 combustion potential: extreme events in laminar premixed burners and flame stability in non-premixed swirled injectors" IMFT and CERFACS continue to develop an intense joint work on hydrogen flames, initiated during the ERC advanced grant SCIROCCO (cerfacs.fr/scirocco) and continued through multiple collaborations with SAFRAN, AIRBUS and other companies.

ISAF project : To accelerate the transition to SAFs, SAFRAN and CERFACS have together obtained an allocation of 44 million CPU hours on the LUMI-C super-computer as part of the EuroHPC Regular Access call in November 2022.
11 March 2023
The objective of the ISAF project is to study the impact of SAFs (Sustainable Aviation Fuels) on engine operation and pollutant emissions, using high-fidelity Large Eddy Simulations (LES). The methodology developed at CERFACS combines Analytically Reduced Chemistry (ARC) with a multi-component evaporation model to capture the effect of fuel. The target configurations range from academic burners (CRSB at CORIA, SSB at DLR Stuttgart), to isolated industrial injection systems (MICADO at ONERA, HERON at CORIA) and complete annular combustor configurations (BEARCAT at SAFRAN, NTNU test bench).

Workshop INTEL ONEAPI
21 February 2023
Purpose of workshop Take advantage of architectures with new programming paradigms In recent years computation has been exposed to a widely growing heterogeneity of the types of used devices and their manufacturers. This trend is driven by the specialisation of devices to fit the needs of specific workloads, which in turn is the strategy to satisfy the ever-growing demand in compute power. Heterogeneity is present in both high-performance computing and consumer electronics. Today's systems use a multitude of co-processors and accelerators, such as GPUs, TPUs, and FPGAs, in addition to the traditional CPU. However, there isn't a simple, portable and efficient method to develop for these systems. Intel oneAPI (SYCL implementation) aims to fill this role. Getting the maximum achievable performance out of today’s hardware is a fine balance between optimal use of underlying hardware features and using code that is portable, easily maintainable, and power-efficient. These factors don't necessarily work in tandem. They require prioritizing based on user needs. It's non-trivial for users to maintain separate code bases for different architectures. A standard, simplified programming model that can run seamlessly on scalar, vector, matrix, and spatial architectures will give developers greater productivity through increased code reuse and reduced training investment. People Researchers and engineers with HPC knowledge Dates 28, 29, 30 March 2023 Duration 3 days with sessions training Program is available here Registration Free but Mandatory, please send an email to dast@cerfacs.fr The workshop takes place at CERFACS and course language is French and english.
