Abstract :
We studied mass and heat transfer during nonisothermal desorption of a solvable dielectric gas to a stagnant bubble from a surrounding gas-saturated dielectric liquid under the influence of the alternating electric field. Mass flux is directed from a host fluid to bubble, and the applied electric field causes a creeping flow around the bubble. The moving boundary problem is solved in the approximations of a thin concentration and temperature boundary layers and finite dilution of an absorbate in the absorbent. The nonlinear partial parabolic differential equations of mass and energy conservation are solved by means of a generalized similarity transformation, and the solution is obtained in a closed analytical form for all frequencies of the applied electric field. Numerical calculations show an essential (by a factor of 2÷3) enhancement of the rate of mass transfer in sulfur dioxide-water system under the influence of alternating electric field for a stagnant bubble.
