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…
Evidence of convective rolls in a sunspot penumbra
V. Zakharov, J. Hirzberger, T. L. Riethmueller +2
aims: We study the recently discovered twisting motion of bright penumbral filaments with the aim of constraining their geometry and the associated magnetic field. methods: A large…
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…
