纳米粗糙表面上的润湿

Wetting on Nanorough Surfaces

Thierry Biben, Laurent Joly

摘要:

在这封信中,我们提出了一个自由能的方法来纳米结构表面附近的流体动力学。该模型既考虑了表面附近的静态相平衡(润湿角,Cassie-Wenzel转变),也考虑了边界处的动态性质,如液体滑移。这种方法弥合了唯象相场方法和更宏观的格子玻尔兹曼模型之间的差距。

英文摘要:

We present in this Letter a free-energy approach to the dynamics of a fluid near a nanostructured surface. The model accounts both for the static phase equilibrium in the vicinity of the surface (wetting angles, Cassie-Wenzel transition) and the dynamical properties like liquid slippage at the boundary. This method bridges the gap between phenomenological phase-field approaches and more macroscopic lattice-Boltzmann models.
