Absorption of water vapor into wavy-laminar falling film of aqueous lithium-bromide

Abstract

Absorption processes of water vapor into lithium bromide-water solution film inside a vertical tube were studied experimentally. The heat and mass transfer coefficients were measured as a function of film Reynolds number in the range of 30–200. The variables considered were system pressure, coolant and solution temperatures whose differences were kept constant. Optimum film Reynolds number was found to exist for a maximun heat and mass transfer. © 1995, The Korean Society of Mechanical Engineers (KSME). All rights reserved.
