NONSTRUCTURED FINITE-VOLUME ALGORITHM FOR SIMULATING TURBULENT FLAMESIN INFINITELY RAPID CHEMISTRY

We present here a numerical algorithm based on a non structured finite element volume method. The algorithm resolves the Navier-Stokes equat ions coupled to the K-epsilon model, for the turbulence modelling, and the MIL model for the turbulent combustion modelling. We approximate the convection terms by upwind schemes. We use a PI finite element for the approximation of the diffusion and the source terms. A semi impli cit robust algorithme has been obtained. Some numerical illustrations are presented in the last paragraph.. (C) Elsevier, Paris.
