J054051 Effects of the Local Non-equilibrium Behaviors Caused by Nanostructures on the Energy Transport at a Liquid-Solid Interface
Year: 2011
Type: article
Abstract: The influences of the structural geometry at the nanometer scale on the thermal resistance at a liquid molecule-solid interface, as well as the interfacial local non-equilibrium behaviors of liquid molecules, were investigated directly by the non-equilibrium classical molecular dynamics simulations. A liquid molecular region confined between the solid walls, of which the interparticle potential was Lennard-Jones model or SPC/E model, was employed as a calculation system. The interfacial thermal resistance was dependent on the surface geometry at the nanometer scale and the interaction parameters between the solid atoms and the liquid molecules. The interfacial thermal resistance at the liquid-solid interface related to the interfacial local non-equilibrium behaviors of the liquid molecules regardless of liquid molecular degrees of freedom. The energy transport mechanism at the liquid-solid interface was changeable depending on the surface geometry at the nanometer scale under the present calculation conditions and it might relate to the variations of the interfacial thermal resistance and the local non-equilibrium behaviors of the liquid molecules at the liquid-solid interface.
