The boiling phenomena of liquid nanofilm on an atomically smooth solid surface with different temperatures are simulated by molecular dynamics. According to the atom and density distributions, transition of boiling models from normal evaporation to explosive boiling is observed, and explosive boiling is triggered when corresponding onset temperature of solid surface is 160 K. An ultra high critical heat flux, approximately 4.2 x 10(8) W m(-2), is determined for the nanofilm boiling of argon on atomically smooth copper surface. Moreover, temperature distribution indicates that the heat transfer of nanofilm boiling on smooth surface is mainly governed by the thermal diffusion mechanism.
