摘　　要：为了研究艏水平舵位置对于艉部流场的影响,将艏水平舵布置在指挥室或主艇体上(分别称为围壳舵和艏舵)。通过对SUBOFF进行数值模拟计算,验证网格划分方式和数值计算方法的正确性,并将该方法应用于围壳舵和艏舵模型。计算结果表明,在采用较好的流线型指挥室的情况下,采用艏舵形式有利于艉部伴流场的均匀性。In order to investigate the impacts of the plane＇s position on the wake flow around the bow of submarine,two models for both the fore hydroplane and sailplane were established based on SUBOFF software,one positioned in the main hull and the other in the sail.Through a numerical simulation,SUBOFF model was computed to validate the method of grid plotting and numerical computation,and then applied this approach to the sailplane and fore hydroplane calculation respectively.The results show that the plane positioned in the main hull with streamlined sail will benefit the uniformity of wake flow.
