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…

Controlling the electrostatic Faraday instability using superposed electric fields
Sebastian Dehe, Maximilian Hartmann, Aditya Bandopadhyay +1
When the interface between a dielectric and a conducting liquid is excited by an oscillatory electric field, electrostatic Faraday waves can be induced. Here, we study the response…
