Influence of liquid miscibility and wettability on the structures produced by drop-jet collisions
David Baumgartner, Ronan Bernard, Bernhard Weigand +3
Collisions between a stream of drops and a continuous jet of a different liquid are experimentally investigated. In contrast to previous studies, our work focuses on the effects of…
Effects of viscosity on liquid structures produced by in-air microfluidics
David Baumgartner, Günter Brenn, Carole Planchette
This paper experimentally investigates the effect of viscosity on the outcomes of collisions between a regular stream of droplets and a continuous liquid jet. A broad variation of…
Universality of stretching separation
David Baumgartner, Günter Brenn, Carole Planchette
We develop a parameter-free model for the fragmentation of drops colliding off-center. The prediction is excellent over a wide range of liquid properties. The so-called stretching…
On the molecular mechanism behind the bubble rise velocity jump discontinuity in viscoelastic liquids
Dieter Bothe, Matthias Niethammer, Christian Pilz +1
Bubbles rising in viscoelastic liquids may exhibit a jump discontinuity of the rise velocity as a critical bubble volume is exceeded. The phenomenon has been extensively investigat…
Miscibility and wettability: how interfacial tension influences droplet impact onto thin wall films
R. Bernard, D. Baumgartner, G. Brenn +3
The influence of miscibility and liquid wettability during droplet impact onto thin wall films is investigated experimentally. Despite similar liquid properties and impact conditio…
A new class of discontinuous solar wind solutions
Bidzina M. Shergelashvili, Velentin N. Melnik, Grigol Dididze +6
A new class of one-dimensional solar wind models is developed within the general polytropic, single-fluid hydrodynamic framework. The particular case of quasi-adiabatic radial expa…
An Extended Volume of Fluid Method and its Application to Single Bubbles Rising in a Viscoelastic Liquid
Matthias Niethammer, Günter Brenn, Holger Marschall +1
An extended volume of fluid method is developed for two-phase direct numerical simulations of systems with one viscoelastic and one Newtonian phase. A complete set of governing equ…
Drop Stream - Immiscible Jet Collisions: Regimes and Fragmentation Mechanisms
Carole Planchette, Hannes Hinterbichler, Günter Brenn
We investigate the collision of a continuous liquid jet with a regular stream of immiscible droplets. The immiscible liquids, namely silicon oil for the continuous jet and an aqueo…
The Onset of Fragmentation in Ternary Drop Collisions
Günter Brenn, Hannes Hinterbichler, Carole Planchette
Recently it has been proposed to use colliding drops for producing advanced particles or well defined capsules, or to perform chemical reactions where the merged drops constitute a…
