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。 In this paper, a new multigrid method is proposed and used to solve the internal flow field in a centrifugal compressor in combination with the explicit time advance method, the finite volume difference scheme and the viscous body force method. The numerical results show that the calculated results by the author’s multi-grid method are in good agreement with the experimental results, and the multi-grid method converges almost twice as fast without the multi-grid method.
