Abstract
Heat transfer across solid-liquid interfaces at the nanometer scale is the important phenomenon in thermal science and engineering. This study examined effects of structures at the atomic scale on heat transfer mechanisms at a solid-liquid interface, using molecular dynamics simulations. As the structures, we adopted the attached atoms: adsorbed or clustered atoms on a flat solid surface, and the thermal transport and interfacial thermal resistance were investigated in detail. The results revealed the enhancement of the thermal transport is remarkable, that is, the thermal resistance is low, for the surface with the adsorbed atoms. The simulations also investigated the thermal transport mechanism from a spectral point of view focusing on the heat flux across the solid-liquid interface. The relationship between the thermal transport and the spectral heat flux was discussed, and the results showed that the thermal transport with the low frequencies is dominant in the case of the surface with the adsorbed atoms.
