Sur un algorithme en volumes finis non structures pour la simulation des flammes turbulentes en chime infiniment rapide

摘要

We present here a numerical algorithm based on a non structured finite element volume method. The algorithm resolves the Navier-Stokes equations 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 P1 finite element for approximation of the diffusion and The source terms. A semi implicit robust algorithm has been obtained. Some numerical illustrations are presented in the last paragraphe.
