液-固界面摩擦的Green-Kubo关系

Green-Kubo relation for friction at liquid-solid interfaces

Kai Huang, Izabela Szlufarska

摘要:

我们已经开发了一个绿色Kubo关系,使精确计算摩擦在固液界面直接从平衡分子动力学(MD)模拟,并提供了一条途径,绕过典型的非平衡MD模拟的时间尺度限制。该理论已被验证了一些不同的接口,它表明,液-固滑移是一个内在的属性的接口。由于我们的方法的高数值效率,它可以用于在水环境中的应用,如纳米和微流体接口的设计。

英文摘要:

We have developed a Green-Kubo relation that enables accurate calculations of friction at solid-liquid interfaces directly from equilibrium molecular dynamics (MD) simulations and that provides a pathway to bypass the time-scale limitations of typical nonequilibrium MD simulations. The theory has been validated for a number of different interfaces and it is demonstrated that the liquid-solid slip is an intrinsic property of an interface. Because of the high numerical efficiency of our method, it can be used in the design of interfaces for applications in aqueous environments, such as nano- and microfluidics.
