A supersonic cascade with chord length of 100.6 mm
inlet and outlet flow angle of 154°
the maximum thickness of 16.8 mm
and vane pitch of 46.4 mm was investigated by FINE/TURBO software
and the results was compared with test data.Results show that
the simulation results accord well with the experimental data in reference [2].The H-O-H type grid has obviously higher quality than that of H type grid.Under large pressure ratio
the simulation error resulted from the Euler equation is bigger than that from the N.S equation.
