Cavitation Tests on an Axial Flow Pump
Bulletin of JSME, 1959 Cavitation tests on an axial flow pump were made over a wide range of operating conditions. Through these tests, the aspects of cavitation in the impeller were observed with a strobolight and variation of the pump characteristics was studied. A parameter σs to represent the suction condition was introduced to give the cavitation limits for any flow ...
