摘　　要：首先对Myring型回转体的阻力数值计算方法进行了讨论。其中着重对回转体周围控制域的网格离散方法及湍流模型的选择进行了讨论。将回转体数值计算得到的结果与实验值进行对比,选出适合的湍流模型,同时验证了计算方法的可行性。其次应用之前提出的数值计算方法,对某型载人潜器的模型进行阻力数值计算,得到相应的阻力系数。最后通过换算得到实艇阻力,并绘制了实艇的有效功率曲线。研究表明,相比于k-ε模型,k-ω模型能更好地计算Myring型回转体的阻力,并且在高雷诺数下有较高的精度,更适宜目标潜器的阻力预报。从目标潜器模型的直航阻力入手,对实艇的阻力进行预报,最后得到其有效功率,为该载人潜器的动力、控制等系统的设计提供了参考。Firstly, the numerical method of Myring type rotary body＇s resistance is discussed The method of grid discrete on control domain surrounding the axisymmetric body and the selection of turbulence model are emphatically analyzed The calculation results are obtained and compared with the experimental data. Thus, an available turbulence model would be selected The calculation results are compared with the experimental data. The feasibility of the calculation method is verified Hereafter, a series of corresponding resistance coefficients can be obtained by calculating the model of a specific type manned submarine＇s resistance. At last, the resistance of real submarine is got by conversion. And the effective power curve of the real submarine is drew. The results show that, comparing k-e model, the drag of Myring type rotary body can be calculated better by k-co model, and more accurate data can be received under the high Reynolds number.. So k-ω model is more plausible for the predication of the aim submersible vehicle＇s drag. Starting with the direct navigation resistance of the aim submersible vehicle model, the drag of real marine is estimated Finally the effective power is obtained and the paper provides references for the design of the power system and control system of manned submarines.
