为计算螺旋桨定常与非定常水动力性能，采用多重参考系模型，利用Reliable k-ε湍流模型计算定常水动力性能，仿真不同进速下螺旋桨的推力系数、转矩系数与敞水效率，将仿真结果与试验值对比，结果表明，采用多重参考系模型计算的推力系数、转矩系数与敞水效率与试验值吻合较好；以定常计算结果为初始值，采用滑移网格模型计算螺旋桨的非定常水动力性能。相比于定常结果非定常结果，与试验值更加吻合，表明滑移网格模型计算的结果精准度更高，更适合于计算螺旋桨的水动力性能。
For the calculation of propeller steady and unsteady hydrodynamic performance, using multiple reference frame model, the calculation of unsteady hydrodynamic performance using Reliable turbulence model, thrust coefficient simulation of different velocity of propeller, torque coefficient and open water efficiency, value comparison, simulation results and experimental results show that the thrust coefficient calculated by multiple reference model, torque coefficient and open water efficiency are in good agreement with the experimental value; to the steady results as the initial value, the unsteady hydrodynamic performance of propeller is calculated using the sliding mesh model. Compared to the results of steady unsteady results and the experimental results show that the calculation results are more consistent, the sliding mesh model precision more and more suitable for the calculation of the hydrodynamic performance of the propeller.
