| Abstract: | In this paper,the hydrodynamic performances of direct flight and oblique towing are simulated and analyzed by using a CFD tool for an L-type podded propulsor working in open-water.The Multiple Reference Frame(MRF) model,the Mixing Plane model,and the Sliding Mesh model are respectively applied to calculate and compare the influences of each model for open-water performance prediction.Based on the results,the variation tendencies of hydrodynamic forces and moments with the helm angle are analyzed. |
