Numerical Analysis Using the Bubble Mass Distribution（BMD）Model for Cavitation Noise by a Marine Propeller

Abstract

The authors developed a new method to analyze underwater radiated noise（URN）by combining the bubble mass distribution（BMD）model with the bubble dynamics and radiation（BDR）model. In this paper, this method was introduced first. As a validation of this method, numerical analysis of cavitation around the Seiun-Maru high-skew propeller II was performed by the BMD model, URN was estimated by the BDR model, and a comparison was conducted between the estimated URN with experimentally-measured URN of the actual Seiun-Maru. Consequently, this method looks very promising.
