Unsteady Hydrodynamic Performance Prediction of Ducted Propeller Based on CFD

Abstract

Firstly, the calculated model was created in UG and GAMBIT, and then the Moving Mesh method was adopted to simulate thrust and torque of ducted propeller using FLUENT in the open water. The thrust, torque and bearing force of ducted propeller in three different wake fields were calculated. And the influence on the performance of ducted propeller by the wake fields was analyzed.

Comparison of Hydrodynamic Performance of Ducted Propeller and Ordinary Propeller on Trawler

“…In ship field, CFD has become an important tool in hydrodynamic research, which can be used to calculate the hydrodynamic performance of ducted propeller and the simulation results are in good agreement with experimental results. Moreover, it can give the details of flow field, the pressure distribution of blade surface and the velocity distribution [1][2][3][4][5][6]. Meanwhile, as the extensively use of large computer and workstation, the commercial CFD software become mature gradually, which overcome the shortcomings of long cycle, high cost and difficult to obtain the flow information of model experiment.…”
