Molecular dynamics simulation on the effect of nanoparticle deposition and nondeposition on the nanofluid explosive boiling heat transfer

Abstract

Molecular dynamics simulations were performed to investigate the effect of nanoparticle deposition and nondeposition on the explosive boiling heat transfer. Both particle state (deposition and nondeposition) and metal surface structure (smooth and rough) were considered to study the boiling behavior. Particularly for the rough surface, a special deposition case was simulated that the deposition nanoparticle was not filled with the pit. The results showed that the addition of nanoparticles enhanced the boiling behavior. The histories of argon temperature, net evaporation number, as well as heat flux demonstrated that deposition nanofluid boiling heat transfer enhancement behavior was the highest.
