Method for calculation of optimum intensity of cavitation influence on viscous and fine-dispersed liquid media

摘要

The article is devoted to the new approach to acceleration of technological processes in viscous and fine-dispersed media due to the influence of high-intensity ultrasonic vibrations, which provides formation of cavitation. It is shown that the existing method for calculation of required power of the ultrasonic technological devices cannot be used for designing special equipment intended for processing of high-viscosity and fine-dispersed liquid media. The improved method for calculation of necessary intensity of ultrasonic influence is proposed. In this method cavitation mode takes place in viscous and fine-dispersed media in order to reveal required power operating conditions of the ultrasonic electronic generators. The obtained results allows recommending the choice of optimum intensity (up to 30 W/cm2) of the ultrasonic influence in liquids with the viscosity of up to 0.6 Pa·s (oil, glycerin, epoxy resin and others), which are widely used in the practice.
