A mathematical model of heat and mass transfer process in plate falling film absorber with wire-meshed fins was developed. The model could predict temperature and concentration distribution as well as the solution side heat transfer coefficient and the absorption rate. The results verify that heat and mass transfer performance of the plate falling film absorber with wire-meshed fins is better than the past absorber. Compared with the plate falling film absorber without fins, heat transfer coefficient of the absorber in this article increases 1.06 times and the absorption rate increases 2.32 times.

In the present study, CFD analysis of falling film type liquid desiccant dehumidifier is carried out to predict its performance In these simulations it is studied how the flow pattern of liquid desiccant effects the interaction between the moist air and the liquid desiccant.Two dimensional model was simulated by using the software ANSYS (FLUENT). The volume of fluid (VOF) was selected as the multiphase method for the simulation process. The water vapor/humidity content in the air is given by using species transport model and the variation of amount of water hold by the air is simulated. The liquid desiccant considered for study is LiCl with 30% concentration and the mass fraction of water vapor used in air is varied from 0.01 to 0.02. The properties of LiCl at 30% concentration were calculated and inlet parameters of air and desiccant are fed to the software as input. The model was subjected to different inlet mass fractions and determined the dehumidification effectiveness.
