A high speed compressor cascade flow is simulated with one linear Eddy Viscosity and one nonlinear Reynolds Stresses turbulence model.Through comparing and analyzing the numerical results,accuracy of the two turbulence models is evaluated.Both the Eddy Viscosity Model and Reynolds Stresses Model are capable of capturing the main flow structures in the high speed compressor cascade flow passage.However,the ignorance of turbulence anisotropic,non-equilibrium and energy backscatter leads to the underestimation of flow separation by Eddy Viscosity Model.For the Reynolds Stresses turbulence model,anisotropic characters of turbulence are taken into consideration which leads to numerical results with higher accuracy.
