Abstract
In the article the results of theoretical investigations aimed at reveal of possibilities of providing maximum size of cavitation zone in limited volumes during ultrasonic influence on technological media having high viscosity or high concentration of dispersed phase are presented. To find out optimum conditions (geometrical dimensions and forms of technological volume) and modes (intensity) of ultrasonic influence on different in viscosity and acoustic properties of liquid mathimatical modeling of the dynamics of the cavitating medium was carried out. Proposed approach to the modeling is based on numerical steam-gas-liquid medium developed on well-known models of microscopic process of extension and collapse of single cavitation bubble. Obtained results allow to recommend the choice of specialized technological volumes and optimum intensities of influence.
