摘要
本文根据Viviand等人提出的求解平面流动问题的拟不定常时间推进法的思路,推导了完整的求解平面叶栅无粘非等熵拟不定常流动的方程系统,应用经过改进了的有限控制面积时间推进格式进行了数值计算。计算结果与精确解或试验结果吻合较好,且能有效地节省计算机时。
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.
