The Measurements of Ultrasonic Cavitation Based on the Image Processing

Abstract

Ultrasonic intensity has a great influence on the concentration of cavitation bubbles. Considering the characteristic of cavitation, in this paper, we propose a method of measuring the amount of cavitation bubbles to identify the change of cavitation intensity indirectly. First, acquires images of reaction liquid under the action of the certain power ultrasonic through machine vision technology; then, obtains micro bubbles quantity generated by ultrasonic cavitation; finally, establish the mathematical model between cavitation intensity and amount of cavitation bubbles to indirectly detect the change of ultrasonic cavitation intensity.
