A molecular dynamics study of local heat transfer at resonant layers of solid–liquid interface

Abstract

Thermal resonance between interfacial layers is essential for near-field heat transfer, while the mechanism underlying interfacial heat transfer remains an open question. This study utilized the volume averaging method to calculate the local heat fluxes at Pt–vacuum and Pt–Ar interfaces in nonequilibrium molecular dynamics simulations. The thermal resonance occurs between the interfacial solid layers, even in the presence of liquid, but it diminishes as the gap between the solid walls widens. At resonant interfacial layers, an excessive local heat flux was observed, while a uniform distribution was found when interfacial resonance was absent. The local heat flux at interfacial solid layers increases with a greater magnitude of thermal resonance.
