Abstract
This paper presents a comparative study of six turbulence models for calculating the diffuser channels of different configurations, and also study of influence of parameters of computational grid on calculation results. The simulations was carried out on six grids with different spacing for the near wall points and different resolutions. The performance of six different turbulence models is compared with experimental results obtained at «Aviamotor» and other published experimental results. Creation of optimal models for different stages of engineering calculations of exhaust systems is considered.
