Process modeling of cavitation zone in process vessels with high-viscous and fine-dispersed liquid media

The article presents the results of theoretical investigations aimed at revealing possibilities of providing maximum size of cavitation zone in limited vessels during ultrasonic impact technological media having high viscosity or high concentration of dispersed phase. In order to find out optimum conditions (geometrical dimensions and forms of process vessel) and modes (intensity) of ultrasonic impact on liquids different in viscosity and acoustic properties, the mathematical modeling was carried out for dynamics of the cavitating medium. The proposed approach to the modeling is based on numerical steam-gas-liquid medium developed on the well-known models of microscopic process of extension and collapse of single cavitation bubble. The obtained results allow recommending choice of specialized process vessels and optimum intensities of impact.
