Abstract

The aim of this work is to improve the efficiency of chemical technology processes implemented in high viscosity or non-Newtonian fluids by identifying modes and conditions of ultrasonic action, which provide an increase in the volume of the cavitation area formed. As a result of the research, a phenomenological model of cavitation area formation in the non-Newtonian medium has been developed. The analysis of the model allows to calculate the optimal intensity of ultrasonic action (for linear-viscous fluids, the optimal intensity ranges from 1.6 to 80 W/cm2; for nonlinear-viscous fluids up to 120 W/cm2) and the distance (60-125 cm) between the irradiating surface and the reflecting boundary providing the maximum cavitation area volume. In finish the model was confirmed experimentally.
