Theoretical and experimental study of cavitation dispersing in 'liquid-solid' system for revelation of optimum influence modes

摘要

The paper contains the results of the study of cavitation dispersing in "liquid -solid" system. It is known that cavitation dispersing is one of energy effective methods of "liquid-solid" interface area increasing. For evaluation of cavitation dispersing modes providing maximum interface area the model of the process was developed. The m odel is based on simulation of bubble collapse near solid particle surface for determination of particle destruction possibility and calculation of particulate composition evolution using of probabilistic approach. Analysis of the model has shown that cavitation dispersing provides increasing a "liquid -solid" interface area up to 2 and more times. The proposed model was confirmed by experiments.
