    摘要:The pool boiling of nanofluids on the metal surface was investigated by
       molecular dynamics simulations to reveal the mechanisms responsible for
       the favorable heat transfer properties of nanofluids. The simulated
       system was consisted by four regions: vapor argon, liquid argon, solid
       copper and nanoparticles copper. Particularly, the nanoparticles were
       placed near the metal surface. Two superheated temperatures were
       considered. The results showed that the fluid temperature and net
       evaporation rate were increased by the addition of nanoparticles. The
       nanoparticles had random movement and did not move with the fluid. It
       was also observed that the nanoparticles size and the superheated
       temperature had significant effect on the enhancement effects.
