摘 要:
实船和船模的螺旋桨噪声存在一定的相似性,通过无量纲分析船模螺旋桨噪声可以预报实船的螺旋桨噪声。本文利用无量纲分析方法,得到影响螺旋桨噪声的一些因素,如雷诺数、桨直径、桨转速、频率、空泡数等。在此基础上对这些因素进行分析,并提出修正方法。[著者文摘]

Abstract:
There is similar performance between ship propeller noise and ship model propeller noise in some degree. Ship propeller noise can be predicted by non-dimensional analysis of ship model propeller noise. Using this method, some factors that influence propeller noise are obtained, such as: Renault number, propeller diameter, propeller rotate speed, frequency, cavitation number and so on. With analyzing those factors, modified methods are put forward.[著者文摘]
