Surface Instabilities and Magnetic Soft Matter
Christian Gollwitzer, Marina Krekhova, Guenter Lattermann +2
We report on the formation of surface instabilities in a layer of thermoreversible ferrogel when exposed to a vertical magnetic field. Both static and time dependent magnetic field…
Measuring the deformation of a ferrogel sphere in a homogeneous magnetic field
Christian Gollwitzer, Alexander Turanov, Marina Krekhova +3
A sphere of a ferrogel is exposed to a homogeneous magnetic field. In accordance to theoretical predictions, it gets elongated along the field lines. The time-dependence of the ela…
Reversing a granular flow on a vibratory conveyor
R. Grochowski, P. Walzel, M. Rouijaa +2
Experimental results are presented on the transport properties of granular materials on a vibratory conveyor. For circular oscillations of the shaking trough a non-monotonous depen…
Axial Sand-Water Segregation
A. P. J. Breu, C. A. Kruelle, I. Rehberg
A novel pattern forming instability in a mixture of a granular material and water in a horizontal rotating drum is experimentally investigated. The particles accumulate in radial s…
