| 摘 要： | 本文利用边界元方法,将平面叶栅可压缩流动的基本方程线性化后,利用非齐次方程特解与齐次方程通解的叠加原理,提出质量点涡的基本概念和公式,将常规奇点法的应用范围从不可压缩流动推广到高亚音速可压缩流动.算例表明,这一方法对高亚音速可压缩流动的计算是成功的,与通常的有限差分法和有限元法相比,具有精度高、速度快、内存少等优点,为叶轮机械准三元流动计算中的s_1流面与s_2流面间的反复迭代提供了一个更有效、更适用的计算工具.

| Abstract: | In this paper the compressible flow past a two dimensional cascade isaccurately computed by means of the boundary element method.The com-puted results given in the paper are in good agreement with experimentaldata.It is seen from the numerical examples that computations in fluidmechanics by means of the boundary element method does not only markedlysave computer time and memory storage,but can also accurately solve theflow near the leading edge of a blade with a bigger thickness. |
