Multiple droplets on a conical fiber: formation, motion, and droplet mergers
Carmen L. Lee, Tak Shing Chan, Andreas Carlson +1
Small droplets on slender conical fibers spontaneously move along the fiber due to capillary action. The droplet motion depends on the geometry of the cone, the surface wettability…
Film coating by directional droplet spreading on fibers
Tak Shing Chan, Carmen L. Lee, Christian Pedersen +2
Plants and insects use slender conical structures to transport and collect small droplets, which are propelled along the conical structures due to capillary action. These droplets…
Droplet Migration on Conical Fibers
Clementine Fournier, Carmen Lee, Rafael Schulman +2
The spontaneous migration of droplets on conical fibers is studied experimentally by depositing silicone oil droplets onto conical glass fibers. Their motion is recorded using opti…
Capillary Levelling of Immiscible Bilayer Films
Vincent Bertin, Carmen Lee, Thomas Salez +2
Flow in thin films is highly dependent on the boundary conditions. Here, we study the capillary levelling of thin bilayer films composed of two immiscible liquids. Specifically, a…
