挥发性薄膜中的粘性指进

Viscous fingering in volatile thin films

Oded Agam

摘要:

解理云母衬底上的薄水膜在两个膜厚度值之间经历一级相变。通过诱导水的有限蒸发速率,两相之间的界面产生了与Saffman-Taylor问题中观察到的相类似的指进不稳定性。我们画出这两个问题之间的联系,并构造描述在这个系统中的蒸发动力学的解决方案。

英文摘要:

A thin water film on a cleaved mica substrate undergoes a first order phase transition between two values of film thickness. By inducing a finite evaporation rate of the water, the interface between the two phases develops a fingering instability similar to that observed in the Saffman-Taylor problem. We draw the connection between the two problems, and construct solutions describing the dynamics of evaporation in this system.
