[Purpose] To enhance the comfort of vessels,vibration level have emerged as a critical parameter for assessing the performance of centrifugal pumps.Once the design and production of a centrifugal pump are completed,postproduction vibration control measures tend to be limited in effectiveness.Consequently,it becomes imperative to effectively suppress flow-induced excitation during the design stage. [Method] Based on the internal flow characteristics of the impeller,this paper takes the jet-wake structure at the impeller outlet as the research entry point,analyzes the generation mechanism of secondary flow within the impeller,and clarifies the influence mechanism of potential flow and wake effects on the unsteady flow field.[Result] The results show that it is necessary to clarify the induction mechanism of blade passing frequency excitation in centrifugal pumps and systematically summarize the flow-induced excitation control methods targeting the suppression of rotor-stator interaction. [Conclusion] The research resultss can provide a reference for the hydraulic design of low-noise marine centrifugal pumps.
