In the basis of many advanced industrial technologies there are such thermodynamic processes occurring on the surface of gas-particle bubbles as absorption [16], aeration [13], bubbling [9], vacuum distillation [5], degassing [3], boiling [18], cavitation [12], the production of heat-insulating materials by the method of blowing [19], gas hydrating [11], and many others. Active studies of the bubbles effect on sound vibrations were carried out to optimize the sonar operation. Existing literature [1, 4] highlights the issue of the damped oscillations at frequencies from 4 kHz to 150 kHz in seawater at different depths. Another direction of research was caused by the need for the use of cavitation [14]. The study of fluid degasification by cavitation method was carried out at frequency from 10 kHz to 1 MHz. In most cases, bubbles oscillation is damping. However, definitely during these oscillations, the most intense heat and mass exchange processes on the bubbles surface are observed. In the course of oscillation, there is a very rapid change in the thermodynamic parameters of the system "gas bubble-liquid". The urgency of the study of heat and mass transfer processes dynamics on the oscillating gas bubble surface is due to the need to optimize various technological processes.
