Molecular dynamics study of scale effect on Kapitza length at solid−liquid interface

Abstract

Thermal energy transport at solid–liquid interface is a crucial issue in advancing the performance of electronic devices. Notably, interfacial thermal resistance, characterized by the Kapitza length (i.e., thermal slip length), significantly governs convective heat transfer in micro/nanochannels. However, there is still a lack of a full understanding of the Kapitza length at the solid–liquid interface. Therefore, we conducted nonequilibrium molecular dynamics simulations to clarify the scale effect on the Kapitza length at the solid–liquid interface.
