APPLICATION OF EARSM TURBULENCE MODEL TO SIMULATION OF REACTING FLOW FIELD IN JETIS COMBUSTION CHAMBER

Popis výsledku v původním jazyce

This paper is interested in the mathematical modeling and approximation of the reacting turbulent flow field with strong anisotropy in a JETIS combustion chamber. Turbulent models based on Boussinesq eddy viscosity assumption or Large Edgy Simulation aretraditionally employed for the solution of these types of flows. Linear eddy viscosity model and the assumption of isotropic Reynolds stress tensor are typically used in many industrial cases. This leads to certain limitations such as lower accuracy ifmodel of turbulence is based on Boussinesq assumption or higher time consumption in the case of LES model. Therefore the effect of Explicit Algebraic Reynolds Stress Model (EARSM) is study in this paper. This model is based on two equations k - omega turbulence model with the nonlinear eddy viscosity model and explicit terms for anisotropic parts of the Reynolds stress tensor with computational requirements similar to the standard k - omega model. The EARSM turbulent model is validated v
