Evaporation and condensation near the triple phase contact line is important for the heat and mass transfer at the micro-nano scale. In the present work, non-equilibrium molecular dynamics simulations (NEMD) were conducted to investigate the evaporation and condensation in thin liquid films at a triple phase system. The simulation domain was a cuboid with periodic boundary conditions. All the three phases were made up of Lennard-Jones molecules (platinum and argon). As solid walls were set with different temperatures, a non-equilibrium state system was established. Intensive evaporation and condensation through the thin liquid films were observed. The evaporation mass flux, the non-evaporation region on the heating wall and the related disjoining pressure were discussed and compared to theoretical results.
