This paper puts forward a new multiple gird scheme, which is used with the combination of explicit time marching method, finite volume difference code and distributed body force.
提出了一种新的与显式时间推进法、有限体积差分格式、粘性体积力法有效地配合使用的多重网格法来求解叶轮机械可压流动。
The mesh used in the code is signed by Finite Control Volume method. Power Law Difference Scheme(PLDS) used in the calculation not only is simple but also has high precision.
采用PLDS法进行数值插值，这种插值方法不但较为简单，而且计算精度高，优于传统的中间差分法；
