Abstract
A computational study is reported on the combined heat and mass transfer during evaporation of binary liquid film. The binary film is falling down on a vertical channel by mixed convection. The first plate is submitted to a constant heated flux while the other is isothermal and dry. The liquid mixture consists of ethylene glycol and water while the gas mixture is made up of three components: water vapour, ethylene glycol vapour and dry air. The results concern the influence of the operating parameters in the liquid and in the gas on the thickness of the binary liquid film and on the cumulated evaporation rate of binary liquid film.
