925 遠心羽根車に生じるキャビテーションの理論解析

Abstract

This paper discribes about theoritical analyses of cavitation in centrifugal pump. A linear stability analysis is carried out by using the singularity method based on a closed cavity model allowing the cavity length freely to change. For 4 bladed impeller, a mode corresponding to the transition to alternate blade cavitation was examined. For 5 bladed impeller, various kind of rotating cavitation was found.
