Simultaneous convective heat and mass transfer during gas bubble dissolution in an alternating electric field

We studied a nonisothermal absorption of a solvable dielectric gas from a stagnant bubble by a surrounding dielectric liquid under the influence of the alternating electric field. Mass flux is directed from a bubble to a host fluid, and the applied electric field causes a creeping flow around the bubble. Bubble deformation under the influence of the electric field is neglected. The problem is solved in the approximations of a thin concentration and temperature boundary layers and a finite dilution of an absorbate in the absorbent. The thermodynamic parameters of a system are assumed constant. 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 showed an essential (by a factor of 2 divided by 3) enhancement of the rate of mass transfer in nitrogen-water system under the influence of alternating electric field for a stagnant bubble. The asymptotics of the obtained solutions are discussed.
