| Abstract: | In this paper, the hydrodynamic performances are simulated by using a CFD tool for an L-type podded propulsor working in open-water, without and with helm angles. The Multiple Reference Frame (MRF) model, the Mixing Plane model, and the Sliding Mesh model are used to study the accuracy and efficiency of each model for open-water performance prediction. Based on the simulation results at azimuthing conditions, the variation tendencies of hydrodynamic forces and moments with the helm angle are analysed. |
