Bulging and buckling of a hose under pressure

Author: Claas Bierwisch
The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves downward through the pipe thereby pushing the fluid into the hose which is sealed by a disc at the lower end. The hose bu ... more

Drying drop on a substrate: The coffee stain effect

Author: Thomas Breinlinger
This video shows the drying of a silver ink micro droplet on a solid substrates. The simulation is carried out using the discrete element method (DEM) which is combined with an analytic solution of the fluid motion via one-way-cou ... more

Sweeping granular matter with a flexible lamella

Author: Claas Bierwisch
The movie shows lamellas of different flexibility which are used to sweep cohesive granular matter by a lateral movement. The effectivity of the sweeping depends strongly on the rigidity of the lamella. Cleaning processes are appl ... more
