Abstract

Simple models of non-isothermal absorption for small and large times have been used to analyze the impact of heat release and heat removal on the intensity of vapor absorption by a motionless layer of solution, not containing surfactants. We consider the models with and without account of displacement of the interface. The results of comparison of calculations with experimental investigations of water vapor absorption by a motionless layer of aqueous solution of lithium bromide are presented. Some problems and contradictions in the existing models, describing heat and mass transfer during absorption of vapors by surfactant-containing solutions are analyzed. A method for determining the gradients of surface tension and the Marangoni criteria in conditions of a heat pump operation is proposed.
