液固摩擦系数的Green-Kubo关系

On the Green-Kubo relationship of the liquid-solid friction coefficient

Lydéric Bocquet, Jean-Louis Barrat

摘要:

在本文中,我们提出了一个新的推导格林-久保关系的液-固摩擦系数,表征流体动力学滑移在一个壁。它是基于一个一般的朗之万方法的脉动壁速度,涉及一个非马尔可夫记忆内核消失的时间积分。计算突出了一些微妙的壁面液体动力学,导致超扩散运动的波动壁面位置。

英文摘要:

In this paper, we propose a new derivation for the Green-Kubo relationship for the liquid-solid friction coefficient, characterizing hydrodynamic slippage at a wall. It is based on a general Langevin approach for the fluctuating wall velocity, involving a non-markovian memory kernel with vanishing time integral. The calculation highlights some subtleties of the wall-liquid dynamics, leading to superdiffusive motion of the fluctuating wall position.
