纳米图案化表面制造的进展引发了人们对研究表面拓扑结构对液-固界面（LSI）传热的影响的兴趣。在这项研究中，分子动力学（MD）模拟进行检查的表面纳米图案化的热阻在LSI的影响。结果表明，纳米图案化可以强烈影响润湿行为和振动特性的固体表面。这两个因素的组合对吸附的液体和固体表面之间的振动耦合的程度有直接的影响。这种耦合和由此产生的LSI热阻之间存在很强的相关性。
Advances in nanopatterned surface fabrication have sparked an interest in studying surface topology effects on heat transfer across liquid-solid interfaces (LSIs). In this study, molecular dynamics (MD) simulations are conducted to examine the effects of surface nanopatterning on the thermal resistance across LSIs. It is shown that nanopatterning can strongly influence the wetting behavior and vibrational properties of a solid surface. The combination of these two factors has a direct effect on the degree of vibrational coupling between the adsorbed liquid and the solid surface. A strong correlation exists between this coupling and the resulting LSI thermal resistance.
