Summary

Heat and mass transfer processes were experimentally investigated for the case of water absorption into aqueous solutions of lithium bromide flowing over a flat plate. Variables considered are inlet solution flow rate, concentration of an additive, and inclination angle of the plate. The use of 2-ethyl-1-hexanol as an additive results in about a four-to five-fold improvement in absorption rate. The occurrence of surface disturbance dose not have a direct connection with the solubility limit of the additive. The cause of the surface disturbances in the presence of additives was investigated through experiments for pool absorption. By regulating the flow of water vapour, the form of the Marangoni convection can be controlled. A qualitative discussion of additives in the role of inducing surface disturbances is presented.
