Abstract
An attachment of inducer is a powerful method to improve the cavitation performance of a turbo-pump. Cavitation surge phenomena, occurring under the severe suction pressure at partial flow rate, is focused in the present paper. Flow measurements were carried out at the inlet and outlet sections of a flat-plate helical inducer with the solidity of 2.0 and tip blade angle of 11 degrees byusing a total-head yawmeter with a phase locked sampling method to the cavitation oscillation. Change of the flow distributions during the oscillation is clarified with observed cavitation behaviors. After the results are compared with those at conditions just before and after the oscillation, the fluctuating blade forces are estimated from the blade to blade distributions of casing wall pressures measured at these conditions.
