摘要: 为了进一步优化集成电机推进器设计, 建立了集成电机推进器物理模型和流场数值模型, 确定了边界条件, 利用FLUENT软件对集成电机推进器的流场进行了仿真, 得到了不同工况下定子叶片、转子叶片表面的压力和速度分布情况, 以及集成电机推进器的推力、效率与航速之间的关系。利用仿真结果可对集成电机推进器性能进行估算, 为集成电机推进器的设计和优化提供参考。Abstract: Physical models of an integrated motor propeller and mathematical models of flow field are established, and the boundary conditions are determined to optimize the design of the integrated motor propeller. The software FLUENT is adopted to numerically simulate the inside flow fields. Thus, the distributions of pressure and velocity on the blade surfaces of rotor and stator are obtained, and the relationship among the propulsive thrust and efficiency of the integrated motor propeller and the running speed of a vehicle is gained under different conditions. As a result, the performance of the integrated motor propeller can be estimated on the basis of the simulation results.
