| Abstract: | A set of equations is derived on the base of Viviand's formulation for solving non-isentropic inviscid pseudo-unsteady cascade flows. Numerical solution is obtained by employing the improved time-marching scheme. The calculated results show good agreement with the accurate solution and experimental results. The reduction of calculation time is obvious in comparison with the current time-marching solution of Euler equation. The suggested method is appropriate for the engineering applications. |
