Study on Prediction of Underwater Radiated Noise from Propeller Tip Vortex Cavitation

Takuyoshi Yamada; Kei Sato; Chiharu Kawakita; Akira Oshima

The method to predict underwater radiated noise from tip vortex cavitation was studied. The growth of a single cavitation bubble in tip vortex was estimated by substituting the tip vortex to Rankine combined vortex. The ideal spectrum function for the sound pressure generated by a single cavitation bubble was used, also the empirical factor for the number of collapsed bubbles per unit time was introduced. The estimated noise data were compared with measured ships ones and it was found out that this method can estimate noise data within 3dB difference.
