ISO 20233-1-2018 船舶和海洋技术--船舶设计中螺旋桨空化噪声评价的模型试验方法--第1部分:源级估计 Ships and marine technology — Model test method for propeller cavitation noise evaluation in ship design — Part 1: Source level estimation
This document specifies a model test method for propeller cavitation noise evaluation in ship design.<br />The procedure comprises reproduction of noise source, noise measurements, post processing and scaling. The target noise source is propeller cavitation. Thus, this document describes the test set-up and conditions to reproduce the cavitation patterns of the ship based on the similarity laws between the model and the ship. The propeller noise is measured at three stages. The measurement targets for each stage are propeller cavitation noise, background noise, and transmission loss. For the source level evaluations, corrections for the background noise and the transmission loss are applied to the measured propeller cavitation noise. Finally, the full-scale source levels are estimated from the model scale results using a scaling law....
