Flow of asymmetric elongated particles
Bo Fan, Ellák Somfai, Ralf Stannarius +1
Shear induced orientational ordering of asymmetric elongated particles is investigated experimentally. Corn grains and pegs with one end sharpened are studied using X-ray Computed…
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…
Pressure sensitivity in non-local flow behaviour of dense hydrogel particle suspensions
Zohreh Farmani, Nazanin Ghods, Harkirat Singh +5
Slowly sheared particulate media like sand and suspensions flow heterogeneously as they yield via shear bands, in which most strain accumulates. Understanding shear band localizati…
The structure of disintegrating defect clusters in smectic C freely suspended films
Ralf Stannarius, Kirsten Harth
Disclinations or disclination clusters in smectic C freely suspended films with topological charges larger than one are unstable. They disintegrate, preferably in a spatially symme…
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…
Magnetic Resonance Imaging study of sheared granular matter
Jing Wang, Zohreh Farmani, Joshua Dijksman +3
We introduce a Magnetic Resonance Imaging technique to study the geometry of shear zones of soft, low-frictional and hard, frictional granular materials and their mixtures. Hydroge…
