部分润湿流体的接触线运动

Contact line motion for partially wetting fluids

Jens Eggers

摘要:

本文研究了在小毛细数的限制下,靠近前进接触线的流动。为了考虑润湿效应,考虑了对分离压力的长期和短期贡献。在接触线的前面,有一个对应于最小相互作用势的微观薄膜。我们计算的参数的接触线解决方案相关的匹配到一个宏观的问题,例如一个蔓延的液滴。结果非常类似于以前的结果与滑移模型。

英文摘要:

We study the flow close to an advancing contact line in the limit of small capillary number. To take into account wetting effects, both long and short-ranged contributions to the disjoining pressure are taken into account. In front of the contact line, there is a microscopic film corresponding to a minimum of the interaction potential. We compute the parameters of the contact line solution relevant to the matching to a macroscopic problem, for example a spreading droplet. The result closely resembles previous results obtained with a slip model.
