AbstractCavitation surge seems to fall into two types. One is well known as a low cycle oscillation caused by backflow vortex cavitation at lower flow rates and lower NPSH (Net Positive Suction Head). That type is called 'Deep Cavitation Surge (DCS)' in this article. The other is a slight oscillation occurring at higher flow rates and higher NPSP under the influence of fluctuation of the tip leakage vortex cavitation, which will be referred to as 'Slight Cavitation Surge (SCS)'. The present article introduces the results of experiments with SCS, and discusses its origin.
