【摘要】 本文采用摄动法和迭代法,将二维定常可压缩势流的流函数的非线性方程化为线性方程,然后用边界元法求解。分别计算翼型绕流和平面叶栅流动问题,计算结果与实验和其他方法的结果进行比较,结果是满意的。更多还原

【Abstract】 By use of the perturbation method and on iterative process, the non-linear stream function equation for two dimensional compressible potential flowis simplified into linear equations, which are then computed numerically withthe boundary element method. The flow passing an airfoil and the cascades arecomputed respectively. The results are compared with those obtained by experi-ments and other numerical methods. They prove to be satisfactory.更多还原
