| 摘 要： | 回顾了离心泵噪声研究的国内外现状。首先总结了离心泵噪声的来源，并对离心泵噪声来源的研究进行分类评述：机械结构影响离心泵噪声的研究，包括蜗壳几何形状与叶轮影响离心泵噪声的研究；流体动力影响离心泵噪声的研究，包括对汽蚀、流固耦合与湍流诱发噪声的研究。而后从离心泵诱发噪声的数学模型推导、数值计算与试验研究三个方面对研究离心泵噪声所使用的方法进行了总结；最后讨论了目前研究存在的一些问题和今后的研究方向。

| Abstract: | Studying on noise of centrifugal pumps was reviewed.Firstly,noise sources of centrifugal pumps were summed.And studying on noise sources of centrifugal pumps was also classified according to noises from mechanisms including volutes with different geometric shapes and impellers and according to noises from hydrodynamic effects including cavitation,fluid-structure interaction and turbulence.Then,methods used in these studies were summarized in three aspects,namely,theoretical deduction of simplified models,nu... |
