On regular and random two-dimensional packing of crosses
Ralf Stannarius, Jonas Schulze
Packing problems, even of objects with regular geometries, are in general non-trivial. For few special shapes, the features of crystalline as well as random, irregular two-dimensio…
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…
Intermittent flow and transient congestions of soft spheres passing narrow orifices
Kirsten Harth, Jing Wang, Tamás Börzsönyi +1
Soft, low-friction particles in silos show peculiar features during their discharge. The outflow velocity and the clogging probability both depend upon the momentary silo fill heig…
Interacting jammed granular systems
Sára Lévay, David Fischer, Ralf Stannarius +4
More than 30 years ago Edwards and co-authors proposed a model to describe the statistics of granular packings by an ensemble of equiprobable jammed states. Experimental tests of t…
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…
