WebJun 16, 2024 · Furthermore, a macroscopic oil film was left behind on the surface, which indicates that a contact line instability occurred during displacements. The shape of the oil/water meniscus was determined by the balance between viscous forces and capillary forces. The meniscus can be significantly distorted by viscous forces at ultralow IFT. Webidea of a nonlinear instability has been used to explain the disagreement between the predictions of the linear stability analysis and experimental data for the contact line instability in gravity driven spreading of thin liquid films @4#. Non-normality can also arise in the absence of mean ﬂow as a result of localized feedback control @5,6#.

"WebAug 1, 2014 · Contact line instability. In early AC electrowetting studies, Vallet et al. observed an instability of the contact line close to the critical (saturation) voltage for low conductivity liquids such as water [110]. They found that microdrops spontaneously ejected from the contact line as the voltage was larger than a critical value. " - Contact line instability

WebSep 14, 2024 · This paper presents a new kind of instability when inserting a soluble fiber into liquid. After wetting and dissolving the fiber by the liquid, the moving contact line (MCL) spontaneously loses stability. Because the sculpted shape of the fiber looks like a Chinese pagoda, this instability is named as the pagoda instability (PI). WebMay 28, 2013 · As the radius of the cylinder decreases, the modes of perturbation have an increased growth rate, thus increasing cylinder curvature partially acts to encourage the contact line instability. In direct competition with this behavior, a decrease in cylinder radius means that fewer fingers are able to form around the circumference of the cylinder.
