Abstract The mixture of water and ethylene glycol for heat transfer applications was for decades a good choice. In spite of that, the implementation of nanoparticles have made heat transfer fluids even better. Many previous studies assumed the base fluid and nanoparticles as a single-phase. However, two-phase models are being proposed recently. This numerical study aims to investigate the heat and mass transfer intensification of liquid film evaporation in a vertical channel by the use of nanofluids. A two-phase model is used to simulate the nanofluids. A comparison between Ag and Al2O3 nanoparticles is realised to identify the convenient nanofluid. Effects of wall heat flux, inlet liquid mass flow and nanoparticles volume fraction are examined by analysing the enhancement ratios of latent, sensible and accumulated evaporation flow rate.
