Abstract
The purpose of the present study is to investigate numerically the evaporation and condensation of binary liquid film flowing on one of two parallel vertical plates under mixed convection. The results concern the effects of the inlet parameters in the liquid film on the ethylene glycol evaporation and on the water condensation. The results indicate that increasing the amount of liquid film or reducing its inlet temperature benefits the water condensation and disadvantages the ethylene glycol evaporation. It was observed that an increase of the inlet liquid concentration of ethylene glycol enhances the water vapour condensation and the ethylene glycol evaporation.
