Abstract
A model of combined mass and heat transfer during hygroscopic condensation of cold vapor on a hot brine from a single vapor Taylor bubble rising in a channel filled with liquid is suggested. The expressions for coefficients of heat and mass transfer from a single Taylor bubble are derived in the approximations of infinite dilution of absorbate and thin concentration and heat boundary layers in the liquid phase. Two models of combined mass and heat transfer during hygroscopic condensation in vapor-liquid slug flow for cases of high and low Reynolds numbers are suggested. Recurrent relations for mass and heat fluxes from the n-th vapor Taylor bubble are derived. The total mass and heat fluxes in a vapor-liquid slug flow are determined. In the limiting case of absorption without heat release the derived formulas recover the expressions for isothermal absorption in gas-liquid slug flow.
