Cavitation dynamics and flow aggressiveness in ultrasonic cavitation erosion

The mechanisms of cavitation erosion have been the subject of numerous studies, but the cavitation dynamics and flow aggressiveness thereby produced are less known. We develop a new numerical model to capture the cavity evolution and pressure pulsation, which are related to cavitation erosion. The source term in the interphase mass transfer model is obtained from Rayleigh–Plesset equation under the acoustic field. Mathematical closure is...
