Effect of Porous Layer on the Condensation of Falling Liquid Film on a Vertical Channel

In this paper, we numerically investigate the condensation of water liquid film. The results concern the effects of porosity and porous layer thickness of the porous media on the heat and mass transfer performance and on the liquid condensation rate. It is shown that the presence of the porous layer improves the heat and mass transfer at the liquid-gas interface during the water liquid film condensation.
