Cell model for gas absorption with first-order irreversible chemical reaction and heat release in gas-liquid bubbly media

A model for mass and heat transfer during physical gas absorption in gas-li quid bubbly medium suggested in [1] is generalized for a case of chemical a bsorption accompanied by heat release. Diffusion and thermal interactions b etween bubbles are taken in to account in the approximation of a cellular m odel of a bubbly medium whereby a bubbly medium is viewed as a periodic str ucture consisting of identical spherical cells with periodic boundary condi tions at a cell boundary. Distribution of concentration of the dissolved ga s, temperature distribution in liquid and rates of mass and heat transfer d uring nonisothermal chemical absorption of a soluble pure gas from a bubble by liquid are determined. In the limiting case of chemical absorption with out heat release the derived formulas recover the expressions for isotherma l chemical absorption. In the limiting case of physical absorption with hea t release the derived formulas recover the expressions for nonisothermal ab sorption obtained in [1].
