Granular flow modelled by Brownian particles
T. L. Riethmueller, D. Rosenkranz, L. Schimansky-Geier
Granular flows through pipes show interesting phenomena, e.g. clogging and density waves, 1/f-noise. These things are fairly good studied by computer-experiments, but there is a la…

Langevin equation approach to granular flows in narrow pipes
Tino Riethmueller, Lutz Schimansky-Geier, Dirk Rosenkranz +1
The flow of granular material through a rough narrow pipe is described by the Langevin equation formalism. The stochastic force is caused by irregular interaction between the wall…

Recurrent swelling of horizontally shaken granular material
Dirk E. Rosenkranz, Thorsten Poeschel
This Letter reports an experimental study of the dynamics of granular materials when vibrated horizontally. Convective motion is observed over wide range of parameters, similarly t…
