| Summary: | 碩士 === 國立海洋大學 === 系統工程暨造船學系 === 89 === The main purpose of this research is to establish a method to predict the inboard noise of the sister ships using different propulsion power . However , the inboard noise is mainly the broadband noise induced by propeller tip vortex cavitation . The tip vortex index method developed by DNV is adoped and modified to predict the propeller tip vortex cavitation diameter , and the circulation at the propeller tip in the wake field is calculated by unsteady propeller lifting surface theory . Four sister ships of 2200TEU container builded by C.S.B.C. are calculated and compared with measurements . Both results are generally in good agreement .
