This paper deals with a numerical examination of the influence of the water-ethylene glycol composition on the forced convection-evaporation into superheated vapors of a thin liquid film in a horizontal channel. While the other plate of the channel is dry and isothermal, the first plate is externally insulated and covered in a very thin liquid film. Analysis is done on how the composition of the inlet liquid film affects the distribution of velocity, temperature, concentration profiles, and the axial variation of the water evaporation rate. As discovered earlier, this study demonstrates that, starting at a specific value of the ethylene glycol inlet liquid concentration, it is possible to evaporate more water under the same circumstances as if the film at the entry was made of solely pure water.
