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 also analyze the AE characteristics of the impulsive pressures induced by cavitation on the specimen for the impinging jets. Clearly, the energies of high-frequency components in the jets change markedly with injection pressure and standoff distance.
