Influence of interface wettability on explosive boiling of ultra-thin liquid films on a heated substrate using molecular dynamics simulations

Evaporation and explosive boiling of ultra-thin liquid film are of great significant fundamental importance for both science and engineering applications. Wettability, as one of the important properties of solid surface. So it is necessary to understand the influence of wetting property between liquid film and solid surface on explosive boiling. The simulations are carried out for three systems with different solid-liquid interface wettability, from hydrophilic to hydrophobic, to investigate two different boiling phenomena. The jump temperature is set as 300 K for explosive boiling in present study. The results reveal that, with the wettability change from hydrophobic to hydrophilic, the phase transition rate of ultra-thin liquid argon film increases extremely rapidly.
