Abstract

Researches on noise of centrifugal pump are reviewed. Firstly, noise sources of centrifugal pump are summed up. And researches on noise sources of centrifugal pump are also classified by noise from mechanism, including volute with different geometry shapes and impeller, and by noise from hydrodynamics, including cavitation, fluid-structure interaction and turbulence. Then methods used in these researches are summarized by three aspects, namely theoretical deduction of simplified model, numerical model by PC and experiment. At last, some opening issues at present and new fields in future in the researches of noise of centrifugal pump are putted forward.

Key words

centrifugal pump / noise / cavitation / fluid-structure interactions / turbulence / Lighthill / Powell theory / dimensional analysis
