摘　　要：A finite volume program for the calculation of plane cascade flow at large angle-of-attack is developed. The Osher- Chakravarthy 3rd order TVD scheme is used toensure the high accuracy, and the technique of diagonalization is adopted to fast theconvergence speed. Two kinds of non-reflective boundary conditions are explored atthe inlet and outlet boundaries, which can reduce the scale of computational domainand avoid too many grid points for simulations of flow separation and shock waves.A finite volume program for the calculation of plane cascade flow at large angle-of-attack is developed.
