The two dimensional Reynolds-averaged Navier-Stokes equations and the Spalart-Allmaras turbulent model are adopted to simulate the flow fields of the two dimensional flow-paths with three kinds of compression ramp shape in a ram-rotor. It has been found that the compression ramp shape has decisive influence on the form and structure of the shock waves in the two dimensional flow-paths. The overall performance of the flow-path with convex curve compression ramp is optimal.
