The effectiveness of a method for increasing the rate of mass transfer(determining factor in formation of hydrate, utilizing of harmful gases, melts degassing) of gas in a liquid based on the formation of waves on the surface of stable gas bubbles in a liquid during the collapse of cavitation bubbles created by ultrasound has been theoretically substantiated. The three-dimensional numerical model of wave formation on the surface of stable gas bubbles is proposed, which makes it possible to estimate the increase in the interfacial surface area depending on the ultrasonic exposure modes. An assessment of the modes and conditions allowing to achieve the maximum possible increase in the interfacial surface using the ultrasonic method has been performed.
