Vertical Tube, Falling Film Absorption Heat And Mass Transfer Process Enhanced Study

In this study, experiments have been performed for water vapour absorption into falling films of aqueous lithium bromide on vertical copper tubes. 4) 19>( 1 smooth tube and four kinds of heat transfer enhancement tubes were used. From the experimental results of heat and mass transfer, the optimum type of tube of them is opting for the absorber of AHT. By researching into the phenomena of heat and mass transfer between water and lithium bromide, the relationship of the inter-action and inter- affection between heat and mass transfer in a process of non-insulation absorption is theoretically explained. The numerical computation model of heat and mass coupling transfer in a vertical falling film absorber of water-lithium bromide is set up and computed.
