Summary
A model for absorption of water vapor into aqueous LiBr flowing over a horizontal smooth tube is developed. The flow is divided into three regimes: 1) falling film in contact with the tube; 2) drop formation at the bottom of the tube; and 3) drop fall between the tubes. Governing equations are formulated for each flow regime, and the variations of solution temperature, LiBr mass fraction, mass absorption rate and heat transfer rate are discussed including the effect of inlet subcooling. It is shown that the temperature variation across the film exhibits a nonlinear profile near the top of the tube and this effect leads to the necessity of a two-dimensional formulation in the falling film regime for accurate prediction. As has been observed previously, the mass fraction boundary layer at the vapor/liquid interface is found to be very thin and this explains the low absorption flux. The model predicts that significant absorption takes place in the drop formation regime with a considerable variation of temperature and mass fraction.
