    Abstract

    A semi-explicit time marching method is used to solve two13; dimensional Euler equations for a supercritical cascade which was designed by Garabedian and Korn [l] using .complex characteristics. This method was originally developed by M. Couston et al [2]. It is a time dependent damping surface method which gives second order time accurate steady state solution. H-type grid with finite volume formulation is adopted here. For a set of H-type grids, the computed surface Mach number dist ributions are compared with the design values. It is observed that smooth grid produces reasonably accurate solutions13;
