摘　　要：为提高旋转导数的预报精度,以结构化网格为计算背景,采用添加动量源项的方法对旋转导数进行预报,将潜艇旋臂试验的数值模拟转化为定常问题进行求解.分别对SUBOFF裸艇和带附体的情况进行计算,并与试验结果进行对比.结果表明,旋转导数的相对误差在9%以内,满足工程预报要求.To improve the prediction accuracy of rotating hydrodynamic derivatives,an added momentum source method,which transformed the numerical simulation of rotating-arm test from an unsteady problem to a steady one was used to calculate the derivatives of submarine based on structured grid.Bare SUBOFF and SUBOFF with appendages were calculated separately using this method,and the results were compared with experiment ones.Calculation results show that the relative errors of rotating derivatives are lower than 9%,which can meet the requirements of engineering predication.
