EFFECT OF ULTRASONIC CAVITATION ON THE GAS–LIQUID INTERFACE UNDER FORCED AERATION

ABSTRACT A setup for experimental studies of the structure, shape, and size of the gas–liquid interface under ultrasonic exposure and forced aeration has been developed. It has been found that ultrasonic exposure leads to an about 1.5-fold increase in interfacial area during aeration. The ultrasound...

Summary:ABSTRACT A setup for experimental studies of the structure, shape, and size of the gas–liquid interface under ultrasonic exposure and forced aeration has been developed. It has been found that ultrasonic exposure leads to an about 1.5-fold increase in interfacial area during aeration. The ultrasound intensity has been shown to have an optimal value that provides a maximum increase in interfacial area per unit ultrasonic energy input.
