接触角与液固界面热阻关系的分子动力学模拟*OA北大核心CSCDCSTPCD
A molecular dynamics simulation on the relationship between contact angle and solid-liquid interfacial thermal resistance*
本文利用分子动力学方法模拟了液体在固体表面的接触角及液固界面热阻,并探讨了二者之间的关系。通过分别改变液固结合强度和固体的原子性质来分析接触角和界面热阻的关系及变化趋势。模拟结果显示增强液固间相互作用时,接触角减小的同时界面热阻也随之单调减小;而改变固体原子间结合强度和原子质量时,接触角几乎保持不变,但界面热阻显著改变。固体原子间结合强度和原子质量影响界面热阻的原因是其改变了固体的振动频率分布,导致液固原子间的振动耦合程度发生变化。本文的结果…查看全部>>
With the fast development of nanotechnology, the solid-liquid interfacial thermal resistance draws increasing research interest due to its importance in nanoscale energy transport. The contact angle is an important quantity characterizing the interfacial properties and is easy to be measured experimentally. Previous researchers have tried to correlate the contact angle to the interfacial thermal resistance. Using molecular dynamics simulation, we have calc…查看全部>>
