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…
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…
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…
