Abstract: The contribution deals with the numerical simulation of 2D compressible flow through a turbine cascade with smooth and rough blades using the EARSM turbulence model of Hellsten. Predictions were carried out at the Reynolds number Re2is = 850000 for various Mach numbers. The algebraic bypass transition model was applied for comparison in case of smooth blades. Predicted values of the loss coefficient and the flow outlet angle were compared with experimental data for the turbine cascade VS33 with smooth and rough blades of wall roughness.
