基于雷诺平均纳维—斯托克斯（RANS）法，利用SolidWorks和Ansys分别进行螺旋桨建模和水动力计算。在3种不同的湍流模型下分别计算螺旋桨的敞水性能，结果表明SST k-ω模型与试验值贴合较好，为最佳湍流模型。通过对对转桨的桨距比和直径比的研究，得到两者的最优值，在该情况下对转桨的敞水效率最高，并通过尾流分析做了验证。为了比较对转桨与等效单桨的水动力性能，建立了等效单桨模型，在相同的功率系数下做比较，结果表明对转桨在效率提升方面具有明显优势。
SolidWorks and Ansys were used for propeller modeling and hydrodynamic calculation respectively based on RANS. The open water performance of propeller was calculated under three different turbulence models, and the results showed that SST model fited best with test value, which was the optimal turbulence model. Through the study of the pitch ratio and diameter ratio of counter-rotating propellers, the optimum value was obtained, and in this case the open water efficiency of counter-rotating propellers is the highest, then it was verified by the wake analysis. In order to compare with equivalent single propeller hydrodynamic performance of the counter-rotating propeller, the equivalent single propeller model was built, under the same power coefficient comparison, results showed that the counter-rotating propeller had obvious advantages in terms of efficiency.
