摘　　要：开发了二维任意曲线坐标系下、采用同位网格布局、能计算跨音速可压缩流动的SIMPLE方法计算程序。为提高精度,采用QUICK格式、CUI格式在不同的网格分布下计算。为了验证本文方法对低速到跨音速范围内的粘性流动的数值分析效果,对几个典型算例进行了数值试验,计算结果与文献和实验数据吻合较好。A calculational program based on SIMPLE arithmetic is developed to calculate compressible and incompressible flow under arbitrary curve coordinate system. For improving computational precision, the high resolution scheme QUICK and CUI scheme are employed to discretize the convective transport terms under different grid distributing. The agreement between the calculated numerical results and experimental data or other numerical results available in literature is good.
