AB - This paper deals with a numerical analysis of the evaporation of a thin  binary liquid film by forced convection inside a channel constituted by two  parallel plates. The first plate is externally insulated and wetted by a thin  water ethylene glycol film while the second is dry and isothermal. The liquid  mixture consists of water (the more volatile component) and ethylene glycol  while the gas mixture has three components: dry air, water vapour and  ethylene-glycol vapour. The set of non linear and coupled equations  expressing the conservation of mass, momentum, energy and species in the  liquid and gas mixtures is solved numerically using a finite difference  method. Results concerns with the effects of inlet ambience conditions and  the inlet liquid concentration of ethylene glycol on the distribution of the  temperature, concentrations profiles and the axial variation of the  evaporation rate of species i.
