| 摘 要： | 将固体表面分别近似为具有简单的周期性矩形、三角形和半圆形微粗糙结构表面,建立了两相流的晶格玻尔兹曼模型.通过测量不同微粗糙结构表面上液滴的接触角,探讨微结构形状和尺寸的改变对固体材料表面疏水性能的影响.最后,由流体在各种糙壁管中的速度滑移,验证了结论的正确性.

| Abstract: | To study the surface hydrophobicity of solid materials with the lattice Boltzmann method, a rough surface is approximately treated as simple periodic rectangular, saw-tooth and semicircular protrusion structures separately. A two-phase lattice Boltzmann model is used to simulate the change of surface hydrophobicity by calculating the contact angle of a droplet on the rough surface. Finally, the fluid flow in a nano-channel with rough walls is studied. |
