Abstract
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 plates. The first plate is externally insulated and wetted by a thin water ethylene glycol film while the second is dry and isothermal. The first part is concerned with the effects of inlet ambiance conditions and the liquid concentration of ethylene glycol on the distribution of the velocity, temperature, concentrations profiles and the axial variation of the evaporation rate. The second part is focused on the inversion temperature point of the evaporation of binary liquid film. Results show that the inversion temperature phenomenon for the evaporation of binary liquid mixture is observed for high liquid concentration of ethylene glycol. The present results show that in the inlet temperature range considered here, the inversion temperature does not exit for the evaporation of pure ethylene glycol.
