Relation between thresholds of free radical generation and atomization under ultrasound exposure

Abstract The relationship between thresholds of free radical generation and atomization under ultrasound exposure was investigated to elucidate the mechanisms ultrasonic atomization. In experiments gradually increase transducer driving voltage, generation, a quick transition water surface shape from protuberance fountain, had same threshold. using acoustic loading conditions with different shapes also confirmed this fact. Furthermore, focused shadowgram field taken small container that mimics visualized spotty-shaped high-intensity nodes inside near boundary protuberance. These results indicate induction cavitation promoted by triggers appearance fountain leads creation
