论文摘要
移动接触线的分子结构（MCL）和相应的宏观耗散的出现使MCL成为流体动力学的范式。通过消除毛细血管涂抹的新型平均技术，我们在分子动力学（MD）模拟中实现了前所未有的分辨率，发现它们与通过有限元方法（FEM）降低到分子等级获得的连续性描述匹配。这使我们能够区分液体固体界面（Navier-Slip）和接触线处的耗散，而对于所考虑的相当光滑的底物来说，后者可以忽略不计。
The molecular structure of moving contact lines (MCLs) and the emergence of a corresponding macroscopic dissipation have made the MCL a paradigm of fluid dynamics. Through novel averaging techniques that remove capillary waves smearing we achieve an unprecedented resolution in molecular dynamics (MD) simulations and find that they match with the continuum description obtained by finite element method (FEM) down to molecular scales. This allows us to distinguish dissipation at the liquid-solid interface (Navier-slip) and at the contact line, the latter being negligible for the rather smooth substrate considered.
