摘　　要：采用Reynolds平均Navier-Stokes(RANS)方法计算潜艇三维粘性流场,分析潜艇指挥台围壳对潜艇水动力性能的影响。采用全附体SUBOFF模型验证了CFD方法,通过将螺旋桨盘面处的实效伴流场、艇体表面压力分布以及模型总阻力的模拟结果与Taylor船池的实验结果进行对比。比较结果显示CFD计算结果与实验数据具有很好的一致性,表明CFD方法可以用于潜艇指挥台围壳设计的水动力计算。通过数值计算研究指挥台围壳的高度和在艇上的分布位置对其后方的流场、螺旋桨盘面处的伴流场和阻力的影响。The Reynolds averaged Navier-Stokes（RANS） was adopted to calculate the 3-D viscous field around the submarine. And the effect of the submarine sail on submarine hydrodynamic was discussed based on the result. To validate the present CFD code, the SUBOFF model with full appendages was used. The results were compared with experimentally obtained data from Taylor towing tank, including normal wake velocity distribution in the region of the propeller, surface pressure and the total resistance. The good agreement between the computed and measured data demonstrates that CFD code can be used to provide significant hydrodynamics for submarine sail design. Based on the calculation, the effects of some parameters of the sail such as the height, the location and so on were studied on the downstream field, the wake in the region of the propeller and the resistance.
