A Computer Simulation and Experiments to explain the phenomenon of convection rolls in rotating boxes — •Ann-Kathrin Raab^1,2, Adrian Ebert², and Thomas Grillenbeck² — ¹Technische Universität München D-85748, Germany — ²Ignaz-Günther-Gymnasium Rosenheim D-83026, Germany

In an investigation of self-organized pattern formation in rotating packings, several experiments showed a phenomenon which no one can explain yet: In 2D packings sometimes there are convection rolls and sometimes not, whereas in 3D packings the patterns appear every time. A computer simulation should help to find out, whether the pattern building in 2D packings appears spontaneously or if there are any undiscovered circumstances which might lead to convection rolls. By using simple experiments with self constructed packings we will determine possible connections between the 2D simulation and the previous 2D and 3D experiments.
