By taking into account the inhomogeneity introduced by the presence of a solid boundary, slip-flow theory extends the range of applicability of the venerable Navier–Stokes description to smaller scales and into the regime where confinement starts to be important. Due to the inherently atomistic nature of solid–fluid interactions at their interface, slip flow can be described, at least in principle, predictively at this level. This review aims to summarize our current understanding of slip flow at the atomistic level in dilute gases and dense liquids. The discussion extends over the similarities and differences between slip in gases and liquids, characterization and measurement of slip by molecular simulation methods, models for predicting slip, and open questions requiring further investigation.

液体和气体滑流的分子力学

通过考虑固体边界的存在所引入的不均匀性，滑流理论将古老的纳维-斯托克斯描述的适用范围扩展到更小的尺度以及限制开始变得重要的区域。由于固液界面相互作用的固有原子性质，至少在原则上可以在这个水平上预测性地描述滑流。本综述旨在总结我们目前对稀气体和稠密液体中原子水平滑流的理解。讨论范围涵盖气体和液体滑移之间的异同、通过分子模拟方法表征和测量滑移、预测滑移的模型以及需要进一步研究的开放问题。
