| 摘 要： | 本文用时间推进法求解欧拉方程组计算二维平面叶栅绕流问题数值实验是否有多重解现象。计算结果表明,求解欧拉方程组进行流场数值模拟最终收敛与初场无关,不存在解不唯一问题,进而计算初场熵值大小,也发现初场熵值大小不影响终场结果。

| Abstract: | The mutiple-solution phenomenon of steady transonic flow about two-dimensional plane cascade using the Time-Marching method for the Euler equations is examined.Computational result shows that the convergesolution of adopting the approach bears no relation to initial field choice.There,is no nonitaique solution problem.It is also found that the entropy value of,initial fields have no effect upon computing result in the numerical solving of the Euler equations. |
