摘      要：This review mainly summarizes the latest developments in the internal flow field and external characteristics of centrifugal *** particular,the latest findings of centrifugal pumps focused on turbulence and cavitation models,flow visualization methods,and fault detection based on noise and *** external characteristics,cavitation,and vibration of the centrifugal pump were extensively *** addition,advanced multi-objective optimization methods for improving impeller’s efficiency and reducing net positive suction head(NPSH)were *** some progress was made in this field,there remain many unsolved problems,such as monitoring and modeling of cavitation,rotational stall phenomenon,and discrepancies between simulation and *** the future,researchers are encouraged to employ multi-dimensional flow visualization technologies and high-performance computing facilities to advance existing understandings on these issues and create new research directions.

主 题 词：Centrifugal pump Two-phase flow Cavitation Pressure pulsation Multi-objective optimization
