My research focuses on the modeling and the numerical simulation of reactive flows. Since 2000 I am working on reducing the kinetic schemes using tabulation techniques. The method we have developed (FPI) uses flamelet libraries, parameterized by a reduced number of variables to reproduce the effects of detailed chemical kinetics. This method has been coupled with different turbulent combustion models for LES or RANS calculations.
Since 2006, I developed another activity on the multi-physics coupling. In this framework, we have developed a Monte Carlo solver to compute the radiative heat transfer in the combustion chambers. This code is coupled with a LES code allowing correctly calculating the influence of radiation on combustion and walling heat transfer.
As all my activities are strongly linked with simulation, I also developed important skills in the field of supercomputing.
Since 2013, I took the direction of EM2C laboratory UPR 288 CNRS and Ecole Centrale Paris.
