固液界面内における局所熱流束に関する分子動力学解析

We conducted the non-equilibrium molecular dynamics simulations for a system where liquid molecules were sandwiched between two solid walls, and examined the local heat flux defined in a liquid-solid interface by imposing a temperature gradient between the walls. The aim of this study was to reveal the heat flux defined locally in three-dimensional space in a liquid-solid interfacial region, and to obtain an atomistic picture of the heat transfer through the liquid-solid interface based on the local heat flux. The results suggested that the heat flux is not uniform in the plane normal to the heat conduction direction in the liquid-solid interface.
