Instabilities of ring-rivulets: Impact of substrate wettability
Stefan Zitz, Andrea Scagliarini, Johan Roenby
Rivulets and droplets are naturally appearing shapes when small amounts of liquid are deposited on a partially wettable substrate. Here we study, by means of numerical simulations,…
To coalesce or not to coalesce: Droplets and surface tension gradients
Stefan Zitz, Tilman Richter, Konstantinos Missios +1
We numerically study the coalescence dynamics of two sessile droplets with radii . The droplets are placed on top of a rigid substrate with a contact angle of .…
Controlling the dewetting morphologies of thin liquid films by switchable substrates
Stefan Zitz, Andrea Scagliarini, Jens Harting
Switchable and adaptive substrates emerged as valuable tools for the control of wetting and actuation of droplet motion. Here we report a computational study of the dynamics of an…
Lattice Boltzmann simulations of stochastic thin film dewetting
Stefan Zitz, Andrea Scagliarini, Jens Harting
We study numerically the effect of thermal fluctuations and of variable fluid-substrate interactions on the spontaneous dewetting of thin liquid films. To this aim, we use a recent…
