摘要：
Based on simple models of nonisothermal absorption for the cases of long and short times, the effect of the heat‐generation and heat‐extraction rates on vapor absorption by a stagnant solution layer is analyzed. Models taking into account and ignoring the motion of the interface between the phases are considered. Results of an experimental study of steam absorption by a stagnant water/LiBr solution are described. Time dependences of temperatures at various heights inside the liquid layer and of the absorbed mass, and also temperature and concentration profiles at various times, are reported. A comparison of predicted values with experimental data is given.
