Revealing of optimum modes of ultrasonic coagulation of submicron particles and determining of the shape of the aggregates by mathematical modeling

摘要

The article presents the results of studying of the process of aggregate formation at the ultrasonic coagulation of submi-cron particles. The results are obtained on the base of mathematical modeling of translatory motion and rotary motion of the couple of particles under the action of ultrasonic field. The novelty of proposed model is in the fact that specific feature of flow of small-scale particles (less than 1 µm) by continuous medium at the deflection of their form from spherical is taken into consideration. Obtained results let formulating requirements to the radiators of ultrasonic vibrations for realization of the coagulation process with maximum efficiency.
