热渗滑移的分子模拟

Molecular Simulation of Thermo-osmotic slip

Raman Ganti, Yawei Liu, Daan Frenkel

摘要:

热渗透滑移--由沿表面的热梯度引起的流动--是一种众所周知的现象,但奇怪的是,缺乏可靠的分子模拟技术来预测其大小。在这里,我们比较了三种不同的分子模拟技术来计算在一个简单的固体-流体界面的热渗透滑移。虽然我们不期望不同的方法是完全一致的,我们发现,差异几乎没有显着的一系列不同的物理条件,这表明实际的分子模拟热渗透滑移是可行的。

英文摘要:

Thermo-osmotic slip -- the flow induced by a thermal gradient along a surface -- is a well-known phenomenon, but curiously there is a lack of robust molecular-simulation techniques to predict its magnitude. Here, we compare three different molecular simulation techniques to compute the thermo-osmotic slip at a simple solid-fluid interface. Although we do not expect the different approaches to be in perfect agreement, we find that the differences are barely significant for a range of different physical conditions, suggesting that practical molecular simulations of thermo-osmotic slip are feasible.
