Evaporation of the Nanofilm Liquid Inside a Vertical Channel by Mixed Convection

In the present work, a numerical study of evaporation of liquid film with a low nanoparticles volume fraction of copper flowing on one plate of a vertical channel under mixed convection is investigated. The wetted plate is externally subjected to a uniform heated flux or adiabatic while the second one is dry and isothermal. The results concern the effect of nanoparticles volume fraction of added in the water film on the heat and mass transfer and on the water film evaporation. The results show that, the presence of the nanoparticles enhances the performances of the heat and mass transfer and the liquid film evaporation.
