Abstract

It is known that the thermal resistance at a solid-liquid interface is changeable when nanoparticles adhere to a heat transfer surface. This is partially because the liquid density around nanoparticles is changed by the nanoparticle-liquid interaction. In the present study, we conducted nonequilibrium molecular dynamics simulations and investigated the effects of the intensity of nanoparticle-liquid interaction and liquid pressure condition on the liquid density profile and the thermal resistance at the solid-liquid interface. The result shows that the thermal resistance at the solid-liquid interface does not so strongly depend on the pressure condition when the change in the pressure does not influence the liquid density in the nanoparticle layer.
