Numerical Simulation of Steady Hydrodynamic Performance for Integrated Motor Propulsor on CFD

For the integrated motor propulsor, numerical model which integrated the internal and external flow field was established. Computational region discretization was carried out through using high quality multi-block structure grid based on CFD method. The flow field performance was calculated by adopting Reynolds time averaged method, and the steady hydrodynamic calculation was sealed off by using turbulence model. Based on the finite volume method and SIMPLEC algorithm, the pressure and method were coupled. Open water performance curve was given, indicating that the integrated motor propulsor has an ideal balance of performance and preferable efficiency. Pressure distribution along the meridian of blade at various heights has been analyzed. The single stage model was reliable and applicable for the research compared with the results of full stage model.
