Rapid boiling of argon vapor film confined by alternated hydrophobic and hydrophilic structures: Molecular dynamics study

Abstract In this article, molecular dynamics method is used to simulate argon vapor film generated by the heat transfer theory of pure wettability surface and alternated hydrophobic and hydrophilic structures surface rapid boiling. Throughout the simulation process, solid platinum is used for nanostructures and wall surfaces. The shape of the nanostructures is a triangular prism model, and the liquid vapor film is argon atoms. The simulation phase is divided into a relaxation phase and a heating phase. The temperature in the relaxation phase is maintained at 86 K, and the temperature in the heating phase is set to 250 K. The simulation results show that for the alternated hydrophobic structures surface, due to the addition of hydrophobic nanostructures, the force is weakened, and its heat transfer efficiency is lower than that of a pure hydrophilic wall surface. Except for the smooth surface, the evaporation efficiency is lower than that of the pure hydrophilic wall. For alternated hydrophilic structures surface, the evaporation efficiency and heat transfer efficiency are better than pure hydrophobic walls.
