Investigation of enhanced thermal properties of Cu Ar nanofluids by reverse non equilibrium molecular dynamics method

Abstract Nanofluids have attracted more and more concerns own their excellent heat transfer performance in comparison with conventional fluids. In this paper, a reverse non equilibrium molecular dynamics method is presented to analyze the enhanced thermal properties of Cu Ar nanofluids. It is found that the thermal conductivity of Cu Ar nanofluids is sensitive to particle size and volume fraction. Meanwhile, the micro-mechanism of the enhancement of thermal conductivity of Cu Ar nanofluids is analyzed. The results reveal that the nanofluids have some similar microstructure characteristics as crystals. The nanoparticles are more likely to adsorb liquid molecules influenced by the solid-liquid interactions.
