摘要

This study discusses the nucleation of cavitation bubble in ultrasonic-vibration treatment. Different liquids were used to investigate the intensities of cavitation based on the damaged marks displayed on aluminum foil. These damaged marks resulted from a high impulsive pressure, which was developed from micro-jet impacts associated with the action of shock waves. Micro-jets initiated from the collapse of bubble clouds. The intensity of cavitations depended on the physico-chemical properties of various liquids and ultrasonic characteristics, such as the density and viscosity of liquid, ultrasound frequencies and traveling velocity in various liquids, etc. Effects of these factors on the intensities of cavitation bubbles are discussed in this study and kinetic energies of micro-jet impact along with the strain energy of deformed aluminum foil are calculated and compared.
