When elasticity affects drop coalescence
Pim J. Dekker, Michiel A. Hack, Walter Tewes +3
The breakup and coalescence of drops are elementary topological transitions in interfacial flows. The breakup of a drop changes dramatically when polymers are added to the fluid. W…
Theory for the coalescence of viscous lenses
Walter Tewes, Michiel A. Hack, Charu Datt +2
Drop coalescence occurs through the rapid growth of a liquid bridge that connects the two drops. At early times after contact, the bridge dynamics is typically self-similar, with d…
Deformation and relaxation of viscous thin films under bouncing drops
Srinath Lakshman, Walter Tewes, Kirsten Harth +2
Thin, viscous liquid films subjected to impact events can deform. Here we investigate free surface oil film deformations that arise due to the air pressure buildup under the impact…
Self-Similar Liquid Lens Coalescence
Michiel A. Hack, Walter Tewes, Qingguang Xie +4
A basic feature of liquid drops is that they can merge upon contact to form a larger drop. In spite of its importance to various applications, drop coalescence on pre-wetted substr…
Self-organised dip-coating patterns of simple, partially wetting, nonvolatile liquids
Walter Tewes, Markus Wilczek, Svetlana V. Gurevich +1
When a solid substrate is withdrawn from a bath of simple, partially wetting, nonvolatile liquid, one typically distinguishes two regimes, namely, after withdrawal the substrate is…
Sliding drops - ensemble statistics from single drop bifurcations
Markus Wilczek, Walter Tewes, Sebastian Engelnkemper +2
Ensembles of interacting drops that slide down an inclined plate show a dramatically different coarsening behavior as compared to drops on a horizontal plate: As drops of different…
