    Abstract

    In this paper, three distinct solution flow regimes have been identified within the horizontal tube absorber, a falling film regime existing on each coolant tube, a droplet formation regime on the underside of each tube, and droplet free fall from one tube to the next. A numerical model integrating the three flow regimes has been developed for the water vapor/aqueous Lithium Bromide system. Based on absorber mass and energy balances for absorber elements in each regime, a 2D model of the absorption process has been formulated. The model identify the importance of droplet formation in the overall performance of the absorber, providing useful tool to investigate the effect of various flows, pressures, inlet conditions and geometric parameters on absorber performance.
