The Modeling of Absorption in two-Layer System 'Gaseous Mixture-Liquid' Under Ultrasonic Vibrations Influence

摘要

The paper presents theoretical studies of absorption gas mixture separation under ultrasonic vibrations influence, which provides cavitation and acoustic process intensification. The theoretical studies based on diffusion equations with non-isotropic effective d iffusion coefficients determined by acoustics flows and natural diffusion. The proposed model ta kes into account increasing of interface "gas-liquid" area, caused by surface capillary waves provided by shock waves from cavitation bubbles. In result of the studies, it is evaluated, that ultrasonic intensification increases absorption productivity up to 2 times and more with amplitude of vibrations 1…2 μ m. The obtained results can be used for development of h igh-efficiency absorption apparatuses that are supplemented by ultrasonic influence sources.
