摘要
本文集中于研究空泡噪声和使用比例模型来估算螺旋浆和水力机械所产生的噪声。卅多年前,用比例模型及其全尺寸原型所获得的噪声测量,证实了为预报空泡噪声级和频谱所提出的尺度定律。
The paper concentrates on area of cavitation noise research; the use of scale models for estimating the noise generated by cavitating propellers and hydraulic machinery. Noise measurements obtained over 30 years ago with scale models and their full-size prototypes are shown to verify the scaling laws proposed for predicting cavitation noise levels and spectra.
