| 摘 要： | 受英国剑桥大学Denton教授对叶轮机械数值计算的启发,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来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很好,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,也比Denton多重网格法的收敛速度加快了将近1倍.

| Abstract: | Under the elicitation of Professor Denton's effective research of turbomachinery CFD (Cambridge University of the United Kingdom),a new multiple grid scheme is put forward in combination with explicit time marching method,finite volume difference code and distributed body force (by Professor Denton) to calculate the internal flow field of H.Krain centrifugal impeller.The results show that the multi grid scheme greatly improves the converging speed and that the calculation results are consistent with the measurements |
