Abstract

Based on the features of the falling film absorption, a CFD model of heat and mass transfer of falling film absorption in a vertical tube using LiBr /H2O as working fluid was presented. The CFD model using the volume of fluid (VOF) method was presented for predicting the mass-transfer process of the two-phase parallel current falling film, in which a mass-transfer source term and a heat-transfer source term are given. By analyzing the computation results, the distributions of solution temperature and concentration at the interface and bulk are obtained. It also explores that the impact of film fluctuations on temperature and concentration of the interface and the influence of the fluctuation on the heat transfer between solution and cooling water.
