Tip Vortex Index (TVI) Technique for Inboard Propeller Noise Estimation

Öz

Cavitating marine propeller is one of the most dominant noise sources in marine vessels. The aim of this study is to examine the cavitating propeller noise induced by tip vortices for twin screw passenger vessels. To determine the noise level inboard, tip vortex index (TVI) technique has been used. This technique is an approximate method based on numerical and experimental data. In this study, it is aimed to predict the underwater noise of a marine propeller by applying TVI technique for two bladed and three bladed propellers. The hydrodynamic performance of cavitating propeller has been calculated by a potential flow code based on lifting surface method. The effect of cavitation number and propeller rotation speed on sound pressure level has been discussed.
