The evaporation of the liquid droplet on a structured surface is numerically investigated using the lattice Boltzmann method. Simulations are carried out for different contact angles and pillar widths. From the simulation for the Cassie state, it is found that the evaporation starts in a pinned contact line mode. Then, when the droplet reaches the receding state, the contact line jumps to the neighboring pillar. Also, the depinning force decreases with increasing the contact angle or the pillar width. In the Wenzel state, the droplet contact line remains on the initial pillar for all of its lifetime.

水滴在有纹理表面上蒸发过程中接触线的钉扎—钉扎：格子Boltzmann研究

使用晶格玻尔兹曼方法对液滴在结构化表面上的蒸发进行了数值研究。针对不同的接触角和支柱宽度进行了仿真。通过对卡西状态的模拟，可以发现蒸发是在固定接触线模式下开始的。然后，当液滴达到后退状态时，接触线跳至相邻的柱。而且，销钉力随着接触角或支柱宽度的增加而减小。在Wenzel状态下，液滴接触线在其整个生命周期中都保留在初始柱上。
