潜艇水动力系数对其水动力性能研究具有重要意义。为了获取潜艇旋转导数，本文以结构化网格为背景，采用旋转坐标系方法将潜艇旋臂试验数值模拟转化为定常问题，对Suboff裸艇与全附体在 2 种不同的湍流模型下进行数值仿真，并与试验数据对比，发现仿真结果与实际较为相符，其中标准 k-ω 的仿真结果总体优于 RNG k-ω，表明方法可行且拥有较高计算效率。本研究对获取潜艇旋转导数有一定参考价值。
The hydrodynamic coefficients are significant for the hydrodynamic performance of submarine. In order to obtain the rotary derivative of submarine, structural grid and rotating coordinates were adopted to transfer the numerical simulation results of submarine rotating arms to a steady problem. Simulations based on SUBOFF submarine and fully enclosed submarine were performed in two different turbulent models, the results were pretty compatible with the fact. Among the two models, standard k-ω is more accurate than RNG k-ω. This method proved to be reasonable and efficient, which contributes significantly to the research on the rotary derivative of submarine.
