Résumé

The present survey consists of numerical prevision of two turbulent jets with swirling in a combustion chamber. The simulation is based on numerical method of finite volumes and finite differences of Patankar. The mathematicalmodel used is two equations of turbulence model (K-ε). The iterative sequence adopted SIMPLE algorithm for a resolution of equations
system. A calcul is realized by a numerical code adapted to present configuration. The numerical results were compared with experimental results of the literature [6]. Performances of model (K-ε) have examined with another numerical result study such, as the used model is the Reynolds Stress Turbulence Model (RSTM). This model necessitudean important number of equations for a calcul of Reynolds Stress.A good according was qualitatively observed for the predictions of the (K-ε) model.
