Lennard-Jones液体液-固界面的表面张力弛豫

Relaxation of surface tension in the liquid-solid interfaces of Lennard-Jones liquids

Alex Lukyanov, Alexei Likhtman

摘要:

通过分子动力学(MD)模拟中的直接测量,建立了Lennard-Jones(LJ)液体液-固界面的表面张力弛豫时间。主要结果是,弛豫时间被发现是弱依赖于我们的研究中使用的分子结构,并位于这样一个范围内,在缓慢的流体动力学运动的接口预计将处于平衡。动态润湿过程的建模和动态接触角数据的解释,我们的研究结果的影响进行了讨论。

英文摘要:

We have established the surface tension relaxation time in the liquid-solid interfaces of Lennard-Jones (LJ) liquids by means of direct measurements in molecular dynamics (MD) simulations. The main result is that the relaxation time is found to be weakly dependent on the molecular structures used in our study and lies in such a range that in slow hydrodynamic motion the interfaces are expected to be at equilibrium. The implications of our results for the modelling of dynamic wetting processes and interpretation of dynamic contact angle data are discussed.
