Cavitation tests have been carried out for helical inducer with various blade lengths. Effects of inducer blade lengths on head characteristics and cavitation induced oscillation phenomena are described in the present paper. The oscillation occurring in the case of inducers with lower solidity less than 1.0 differs from that with the solidity of 2.0. Change of the flow distributions during the oscillation is measured from by using a single hole yawmcter with the phase locked sampling method to the oscillation. By compared with the results for higher solidity inducer, the behaviors of cavitation induced oscillation are clarified.
