Numerical Simulation of Hydrodynamics for Integrated Motor Propeller

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.
