A numerical solution procedure for Navier-Stokes Equations on unstructured triangulargrid has been developed in this paper. A new type UPWIND scheme proposed by ourselvesis used for invisicid flux computations. Solutions are advanced in time by implicit Gauss-Seidel relaxation procedure. A simple implicit method to boundary is given also. Finally,a turbulent flow in VKI cascade with large head and large attack angle was solved, andcomparisons between computational results and experimental were also provided.
