How geometry determines the coalescence of low-viscosity drops
A. Eddi, K. G. Winkels, J. H. Snoeijer
The coalescence of water drops on a substrate is studied experimentally. We focus on the rapid growth of the bridge connecting the two drops, which very quickly after contact ensue…
Oscillating and star-shaped drops levitated by an airflow
Wilco Bouwhuis, Koen G. Winkels, Ivo R. Peters +3
We investigate the spontaneous oscillations of drops levitated above an air cushion, eventually inducing a breaking of axisymmetry and the appearance of `star drops'. This is stron…
Bubble formation during the collision of a sessile drop with a meniscus
Diederik L. Keij, Koen G. Winkels, Hein Castelijns +2
The impact of a sessile droplet with a moving meniscus, as encountered in processes such as dip-coating, generically leads to the entrapment of small air bubbles. Here we experimen…
Short time dynamics of viscous drop spreading
Antonin Eddi, Koen G. Winkels, Jacco H. Snoeijer
Liquid drops start spreading directly after coming into contact with a solid sub- strate. Although this phenomenon involves a three-phase contact line, the spread- ing motion can b…
Maximal air bubble entrainment at liquid drop impact
Wilco Bouwhuis, Roeland C. A. van der Veen, Tuan Tran +7
At impact of a liquid drop on a solid surface an air bubble can be entrapped. Here we show that two competing effects minimize the (relative) size of this entrained air bubble: For…
Initial spreading of low-viscosity drops on partially wetting surfaces
Koen G. Winkels, Joost H. Weijs, Antonin Eddi +1
Liquid drops start spreading directly after brought into contact with a partial wetting substrate. Although this phenomenon involves a three-phase contact line, the spreading motio…
