| Summary: | 碩士 === 國防大學理工學院 === 造船及海洋工程碩士班 === 100 === A vessel must generate enough thrust to overcome resistance during its movement. Therefore a balance of thrust and resistance could assure a vessel to sail at a certain speed. This study utilizes Finite Volume Method (FVM), as well as Volume of Fluid (VOF) and the Sliding Mesh Model (SMM) to simulate the flow field with respect to resistance and propeller thrust for a full-size vessel motion at free surface. The simulation result is used to investigate ship hull and propeller flow field to derive the relationship between propeller rotation speed and sailing speed of a vessel. In the present research, standardized Troost B-series series propellers have been studied to examine the relationship between pitch ratio, rotation speed, and propeller thrust. The propeller is installed at the stern of the hull to further analyze the influence of wake flow on the propeller’s propulsion performance. The comparison of simulation and experiment results show that the method proposed in this study could effectively predict vessel resistance and propeller thrust, and offers a practical tool for the initial design phase of marine vehicles.
