Abstract

The intensification of physicochemical processes in the sonochemical reactor chamber is widely used in problems of synthesis, extraction and separation. One of the most important mechanisms at play in such processes is the acoustic cavitation due to the non-uniform distribution of acoustic pressure in the chamber. Cavitation has a strong impact on the surface degradation mechanisms. In this work, a numerical calculation of the acoustic pressure distribution inside the reactor chamber was performed using COMSOL Multiphysics. The numerical results have revealed the dependence of the structure of the acoustic pressure field on the boundary conditions for various thicknesses of the piezoelectric transducer. In particular, the amplitude of the acoustic pressure is minimal in the case of absorbing boundaries, and the attenuation becomes more significant as the thickness of the piezoelectric transducer increases. In addition, reflective boundaries play a significant role in the formation and distribution of zones of maximum cavitation activity.
