Hydrodynamic Performance Analysis of Electric POD Propulsor Based on CFD Method

Abstract

This paper analyzed the hydrodynamic performance of POD electric propulsor under the circumstance of different advance ratios. ANSYS-CFX solver was adopted to solve Narvier-Stokes equations with the standard SST turbulence model. The gridded 3-D model of Wageningen B4-70 propeller was implemented in this study as a thrust unit on the based both of push-POD and pull-POD propulsor. The accuracy of the numerical results of B4-70 hydrodynamic performance, including propeller thrust coefficient, torque coefficient and propeller efficiency, were verified by comparing with experimental results of open water test. Numerical analyses of hydrodynamic performance of pull-push POD propulsor were implemented respectively in one propeller revolution. The simulation results were rewarding references for designing electric propulsion system.
