Steering droplets on substrates with plane-wave wettability patterns and deformations
Josua Grawitter, Holger Stark
Motivated by strategies for targeted microfluidic transport of droplets, we investigate how sessile droplets can be steered toward a preferred direction using travelling waves in s…

Droplets on substrates with oscillating wettability
Josua Grawitter, Holger Stark
In recent decades novel solid substrates have been designed which change their wettability in response to light or an electrostatic field. Here, we investigate a droplet on substra…

Steering droplets on substrates using moving steps in wettability
Josua Grawitter, Holger Stark
Droplets move on substrates with a spatio-temporal wettability pattern as generated, for example, on light-switchable surfaces. To study such cases, we implement the boundary-eleme…
