论文摘要
我们研究了单液液滴通过不可侵扰的超疏水多孔培养基的运输问题。开发了机械软体模型,并用于模拟通过随机多孔培养基的孔隙空间推动流体液滴的过程。每个液滴的质量中心的路径线用于计算培养基的曲折。我们的结果表明,基于液滴的曲折度随多孔样品的孔隙率的降低而增加。尽管从定性上讲,这与从流体流中得出的曲折性观察到的行为一致,但这种关系的形式是不同的。
We investigate the problem of transport of a single fluid droplet through a non-wettable superhydrophobic porous medium. A mechanical soft body model is developed and used to simulate the process of pushing fluid droplets through pore space of a random porous medium. Path lines of the center of mass of each droplet are used to calculate tortuosity of the media. Our results show that droplet based tortuosity increases with decreasing porosity of the porous samples. Although qualitatively this agrees with the behaviour observed for tortuosity derived from the fluid flow, the form of this relation is different.
