CERFACS and CNRS perform first-ever Large Eddy Simulation of combustion instabilities in a rocket engine

In a collaborative work with CERFACS, Institut de Mécanique des Fluides de Toulouse, Centralesupelec, ONERA, DLR and TU Munchen, researchers have been able to use the CERFACS LES code AVBP to simulate the instabilities which appear in certain rocket engines under extreme conditions. The simulation was performed thanks to a PRACE allocation of 80 M hours. The massively parallel capacities offered by AVBP have allowed the code to run on 65 536 processors in production mode (the code itself scales up to 200 000 cores) on the Bluegene Q machine of CINECA.
