Cooling of a granular gas mixture in microgravity
Dmitry Puzyrev, Torsten Trittel, Kirsten Harth +1
Granular gases are fascinating non-equilibrium systems with interesting features such as spontaneous clustering and non-Gaussian velocity distributions. Mixtures of different compo…
Secondary flow in ensembles of non-convex granular particles under shear
Mahdieh Mohammadi, Dmitry Puzyrev, Torsten Trittel +1
Studies of granular materials, both theoretical and experimental, are often restricted to convex grain shapes. We demonstrate that a non-convex grain shape can lead to a qualitativ…
Silo discharge of mixtures of soft and rigid grains
Jing Wang, Bo Fan, Tivadar Pongó +6
We study the outflow dynamics and clogging phenomena of mixtures of soft, elastic low-friction spherical grains and hard frictional spheres of similar size in a quasi-two-dimension…
A simple model system for self-propelled particles passing a bottleneck
Mahdieh Mohammadi, Kirsten Harth, Dmitry Puzyrev +3
We study the passage of active and passive granular particles through a bottleneck under gravitational bias. The grains are pharmaceutical capsules with nearly spherocylindrical sh…
Self similarity of liquid droplet coalescence in a quasi-2D free-standing liquid-crystal film
Christoph Klopp, Torsten Trittel, Ralf Stannarius
Coalescence of droplets is an ubiquitous phenomenon in chemical, physical and biolog-ical systems. The process of merging of liquid objects has been studied during the pastyears ex…
Marangoni flow in freely suspended liquid films
Torsten Trittel, Kirsten Harth, Christoph Klopp +1
We demonstrate controlled material transport driven by temperature gradients in thin freely suspended smectic films. The films with submicrometer thicknesses and lateral extensions…
Wrinkling of freely floating smectic films
Kirsten Harth, Torsten Trittel, Kathrin May +1
We demonstrate spontaneous wrinkling as a transient dynamical pattern in thin freely floating smectic liquid-crystalline films. The peculiarity of such films is that, while flowing…
Silo outflow of soft frictionless spheres
Ahmed Ashour, Torsten Trittel, Tamas Börzsönyi +1
Outflow of granular materials from silos is a remarkably complex physical phenomenon that has been extensively studied with simple objects like monodisperse hard disks in two dimen…
Free Cooling of a Granular Gas in Three Dimensions
Kirsten Harth, Torsten Trittel, Sandra Wegner +1
Granular gases as dilute ensembles of particles in random motion are not only at the basis of elementary structure-forming processes in the universe and involved in many industrial…
Realization of hydrodynamic experiments on quasi-2D liquid crystal films in microgravity
Noel A. Clark, Alexey Eremin, Matthew A. Glaser +9
Freely suspended films of smectic liquid crystals are unique examples of quasi two-dimensional fluids. Mechanically stable and with quantized thickness of the order of only a few m…
