Abstract

Good understanding of In-Cylinder Fluid Flow during the operation process has effective role in the engine design. To aid the best operation, fuel consumption and environment pollution must be decreased. In recent years, various turbulence models are widely developed and used to predict the flow turbulence. In this paper, the effect of turbulence models in simulation of In-Cylinder fluid flow in a combustion chamber has been investigated from the Inlet Valve Closing (IVC) to Exhaust Valve Opening (EVO) . Comparison of the present simulation with the experimental data shows a considerable difference for various models. The results of simulation show that the Reynolds Stress Turbulence Model is better than the other turbulence models.
