Velocity Distribution of a Homogeneously Cooling Granular Gas
Peidong Yu, Matthias Schröter, Matthias Sperl
In contrast to molecular gases, granular gases are characterized by inelastic collisions and require therefore permanent driving to maintain a constant kinetic energy. The kinetic…
Influence of mineralization and injection flow rate on flow patterns in three-dimensional porous media
R. Moosavi, A. Kumar, A. De Wit +1
Reactive flows inside porous media play an important role in a number of geophysical and industrial processes. Here we present three-dimensional experimental measurements on how pr…
Skinny emulsions take on granular matter
Anaïs Giustiniani, Simon Weis, Christophe Poulard +4
Our understanding of the structural features of foams and emulsions has advanced significantly over the last 20 years. However, with a search for "super-stable" liquid dispersions,…
Structural similarity between dry and wet sphere packings
Simon Weis, Gerd Schröder-Turk, Matthias Schröter
The mechanical properties of granular materials change significantly in the presence of a wetting liquid which creates capillary bridges between the particles. Here we demonstrate,…
Double origin of stochastic granular tribocharging
Jan Haeberle, André Schella, Matthias Sperl +2
The mechanisms underlying triboelectric charging have a stochastic nature. We investigate how this randomness affects the distributions of charges generated on granular particles d…
Charging changes contact composition in binary sphere packings
Andre Schella, Simon Weis, Matthias Schroeter
Equal volume mixtures of small and large polytetrafluorethylene (PTFE) spheres are shaken in an atmosphere of controlled humidity which allows to also control their tribo-charging.…
Onset of mechanical stability in random packings of frictional spheres
Melissa Jerkins, Matthias Schröter, Harry L. Swinney +3
Using sedimentation to obtain precisely controlled packings of noncohesive spheres, we find that the volume fraction of the loosest mechanically stable packing is in…
Geometry-induced asymmetric diffusion
Robert S. Shaw, Norman Packard, Matthias Schröter +1
Past work has shown that ions can pass through a membrane more readily in one direction than the other. We demonstrate here in a model and an experiment that for a mixture of small…
Phase transition in a static granular system
Matthias Schröter, Sibylle Nägle, Charles Radin +1
We find that a column of glass beads exhibits a well-defined transition between two phases that differ in their resistance to shear. Pulses of fluidization are used to prepare stat…
Mechanisms in the size segregation of a binary granular mixture
M. Schröter, S. Ulrich, J. Kreft +2
A granular mixture of particles of two sizes that is shaken vertically will in most cases segregate. If the larger particles accumulate at the top of the sample, this is called the…
