Abstract: In this paper, we numerically investigate the improvement of the heat and mass transfer during the evaporation of a liquid film by introducing nanoparticles inside a liquid film. Compared to the liquid case, the use of the nanoparticles added in the liquid film promotes the heat and mass transfer. This improvement is greater when we increase the nanoparticle volume fraction in the liquid film. We also showed that the Cu nanoparticles present the best choice in term of heat and mass exchange compared to Al nanoparticles.
