摘      要：The intensification of physicochemical processes in the sonochemical reactor chamber is widely used in problems of synthesis,extraction and *** 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 *** has a strong impact on the surface degradation *** this work,a numerical calculation of the acoustic pressure distribution inside the reactor chamber was performed using COMSOL *** numerical results have revealed the dependence of the structure of the acoustic pressure field on the boundary conditions for various thicknesses of the piezoelectric *** 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 *** addition,reflective boundaries play a significant role in the formation and distribution of zones of maximum cavitation activity.
