Nonequilibrium molecular dynamics (NEMD) is carried out to investigate the normal and explosive boiling of thin film adsorbed on a metal substrate whose surface is structured by an array of nanoscale spherical copper particles. It is found that superheat degree and size of nanoparticles have significant influences on the location of atoms at multiple times and net evaporation rate. For the cases with nanostructure, liquid respond very quickly and evaporation rate increase with increasing the size of particles from 1 to 2 nm while it decreases for particles diameter of 3 nm.
