Solutocapillary bubble centering in a confined ethanol plume in water
Tobias Baier, Steffen Bisswanger, Sebastian Dehe +1
This study investigates the radial centering of gas bubbles within a buoyant plume of ethanol injected into a co-flowing water sheath flow in a vertical capillary. Bubbles nucleate…

Upstream motion of oil droplets in co-axial Ouzo flow due to Marangoni forces
Steffen Bisswanger, Duarte Rocha, Sebastian Dehe +4
To explore the physicochemical hydrodynamics of phase-separating ternary liquids (Ouzo-type), a binary oil-ethanol mixture is introduced into a co-flowing stream of water. Oil drop…

Liquid Surfaces with Chaotic Capillary Waves Exhibit an Effective Surface Tension
Steffen Bisswanger, Henning Bonart, Pyi Thein Khaing +1
The influence of chaotic capillary waves on the time-averaged shape of a liquid volume is studied experimentally and theoretically. In that context, a liquid film containing a stab…
