Numerical modeling of anisotropic turbulence phase flow inside the cylinder using Reynolds stress turbulence model (RSM)

In this paper anisotropic Reynolds stress turbulence model (RSM) in the computational code EPISO actions and results kvarepsilon isotropic model for single phase and diphasic states compared to that have good coordination. The impact of gas-phase turbulent flow inside the engine Ghyrhmsangrd the shape and appearance parameters of the spray, during infiltration, evaporation rates and distribution of fuel vapor with the RSM model has been studied. RSM model results show that during the spray penetration into the lower field of the model prediction seems kvarepsilon. The evaporation rate of spray model RSM Ghyrhmsangrd the combustion chamber more kvarepsilon isotropic model predicts. In fact, shorter length of influence predicted by the RSM model, rooted in higher evaporation rates in this model is.
