Propeller cavitation noise investigations of a research vessel using medium size cavitation tunnel tests and full-scale trials

摘要

The rising environmental awareness of various adverse emissions by commercial shipping has recently targeted Underwater Radiated Noise (URN) due to its potential impact on marine mammals. Amongst the various sources on-board a commercial ship, cavitation is the dominating one following its inception. In order to ensure acceptable noise levels for sustainable shipping, accurate prediction of the noise signature is vital. Within this framework, a widely utilized method for fulf-scale noise prediction is to conduct model tests in cavitation tunnels and to extrapolate to full-scale.
