概要

The source of cavitation nose and its generation mechanism was investigated by measuring pressure fluctuation levels along the impeller casing under various cavitation conditions. The source of cavitation noise is located in an area between the leading edge and at about 30% of the chord length of the impeller blades. Discontinuous Layer between the tip clearance cavitation region and the main flow is one of the factors contributing to cavitation noise generation. The radiation of cavitation noise was also explained by measuring the casing vibration and the air-borne noise caused by cavitation.
