Evaporation and condensation in the presence of binary liquid film flowing on one of two parallel vertical plates by mixed convection have been studied numerically. The first plate is adiabatic and wetted by a binary liquid film while the second one is dry and isothermal. The results concern the effects of the inlet parameters on the ethylene glycol evaporation and on the water condensation. Results obtained show that the increase of the inlet vapor concentration of water benefits its condensation and the increase of the inlet vapor concentration of ethylene glycol inhibits its evaporation.

“…The variation of detailed heat transfer results with a mixed convection parameter, temperature difference and gas concentration were presented, however, the only conclusion about transition to mixed convection that could be drawn was that the mixed convection effect depends on a number of variables. Recent studies [10,11] on condensation with a non-condensable gas employing boundary layer analysis concentrated on different flow configurations, the effects of turbulence, liquidphase inertia and energy convection, and also on solving the full boundary layer equations. None of these recent studies discussed the problem of convection regime identification.…”
