CERFACS is a research organisation that aims to develop advanced methods for the numerical simulation and the algorithmic solution of large scientific and technological problems of interest for research as well as industry, and that requires access to the most powerful computers presently available. It is supported by seven shareholders, namely EADS, Météo-France, EDF, CNES, SAFRAN, ONERA and TOTAL. It hosts several scientific teams covering various topics (climatology, electromagnetism, parallel algorithms, etc.) among which the CFD team is the largest. The main fields of application of the CFD team are turbulent unsteady flows and reacting flows. It has an internationally recognised expertise in combustion and simulation of aeronautical gas turbines. The team has developed a software to compute industrial combustion chambers, used today by numerous research groups in Europe and by industry. The team was the first in the world to perform unsteady simulations of full annular combustion chambers, to study ignition and combustion instabilities.
CERFACS is realising numerical simulation, which will be used to study combustion instabilities in a full annular chamber, ignition / extinction in a 4 sectors configuration and high pressure effects.
