Abstract
The features of the impact of acoustic flow and cavitation created by a traveling ultrasonic wave, which can be used for efficient dissolution of a metal oxide powder, are considered. On the basis of a simplified scheme, which, nevertheless, takes into account all the essential features of the phenomenon under study, exact expressions are obtained for all parameters of stationary vortex motion and cavitation, which fully meet the requirements for proper control of the reaction course. Equations are derived that describe the dissolution kinetics for two typical regimes: developed cavitation and pre-cavitation state. Expressions are found for the time to completion of the process. On the example of these two most typical types of reaction, the conditions are formulated under which it will be possible to fully satisfy the solution of the technological challenges. The methods for the optimal application of the ultrasonic dissolution scheme are presented and those features of its formation that make it possible to control the process are noted. The performed calculations make it possible to select and accurately implement the scheme of acoustic stimulation of dissolution which best corresponds to the expected output results and other processing features.
