WebOur approach is based on a drying-driven dynamic assembly process occurring on a liquid surface with the stripe pattern formed by a new type of contact-line instability. Periodic ordering of NCs is realized on microscopic and nanoscopic scales simultaneously without the need of any specialized equipment or the application of external fields. Webfingering instability at the moving contact line of a spreading thin film. Numerous experimental and analytical/numerical studies have examined the dynamics of a gravity-driven contact line following the famous study of Huppert [9]. Schwartz [10] proved the contact line instability is controlled by surface tension effects. Troian et al. [11 ...

WebExperiments indicate that initially, as the bridge is stretched, the lower contact line slowly retreats inward. However, at a critical radius, the bridge becomes unstable, and the … WebSurface tension at the front is the last key ingredient for a contact line instability, as it allows the fluid to thicken and become unstable. Recent studies have shown that intergranular cohesion can produce an effective … red hot chili peppers walk up songs

WebThe moving contact line of a thin fluid film can often corrugate into fingers, which is also known as a fingering instability. Although the fingering instability of Newtonian fluids has been studied extensively, there are few studies published on contact line fingering instability of non-Newtonian fluids. WebNov 1, 2015 · The moving contact line of a thin fluid film can often corrugate into fingers, which is also known as a fingering instability.

WebSep 15, 2005 · This kind of phenomena is called contact line fingering instability or capillary ridge instability [4–6]. In recent years, investigation on falling liquid films is mainly focusing on more features of physical interaction, such as electric field [7], Marangoni forcing [8,9], Van-der-Waals forces [10], porous surface [11–13], geometry surface [14] and … rice bowls lohi
