Abstract
In order to establish a useful monitoring method for material erosion caused by high-speed submerged water jets, we clarify the main source of cavitation noises around free jets by using two hydrophones, and al so analyze the AE characteristics of the impulsive pressures induced b y cavitation on the specimen for the impinging jets. Clearly, the ener gies of high-frequency components in the jets change markedly with inj ection pressure and standoff distance.
