Energy analysis in acoustic cavitation

Abstract

In sonochemical processes, the physical and chemical effects are attributed to the phenomenon of cavitation, which is the formation, growth, and collapse of the cavities termed as activity of cavities. Energy analysis of a single cavity has been considered in order to explain, qualitatively, the effects of acoustic parameters such as intensity and frequency of ultrasonic equipment on sonochemical reactions. The experimental observations of the sonochemical reactions available in the literature are found to be consistent with the simulation results. Energy analysis of the cavity gives the possible reasons for the various sonochemical effects observed, and also the optimum equipment operating parameters can be predicted.
