| 摘 要： | 本文提出了一种新的多重网格法，并将之与显式时间推进法、有限体积差分格式、粘性体积力法配合使用求解离心压气机内部流场。数值计算表明，作者多重网格法的计算结果与试验结果吻合比较好，同时该多重网格法的收敛速度比不用多重网格法加快了将近两倍。

| Abstract: | 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. The calculation of a centrifugal impeller shows that the author's multi grid scheme improves the converging speed about three times and that the calculation results fit fairly well with the measurement. |
