The S shape of a granular pile in a rotating drum
Nicolas Taberlet, Patrick Richard, E. John Hinch
The shape of a granular pile in a rotating drum is investigated. Using Discrete Elements Method (DEM) simulations we show that the "S shape" obtained for high rotation speed can be…
Diffusion of a granular pulse in a rotating drum
Nicolas Taberlet, Patrick Richard
The diffusion of a pulse of small grains in an horizontal rotating drum is studied through discrete elements methods simulations. We present a theoretical analysis of the diffusion…
Importance of convection in the compaction mechanisms of anisotropic granular media
Philippe Ribiere, Patrick Richard, Renaud Delannay +1
We report the experimental observation of novel vortex patterns in a vertically tapped granular media. Depending on the tapping acceleration two behaviors are observed. For high ac…
The growth of a Super Stable Heap : an experimental and numerical study
Nicolas Taberlet, Patrick Richard, Etienne Henry +1
We report experimental and numerical results on the growth of a super stable heap (SSH). Such a regime appears for flows in a thin channel and for high flow rate : the flow occurs…
Understanding the dynamics of segregation bands of simulated granular material in a rotating drum
Nicolas Taberlet, Wolfgang Losert, Patrick Richard
Axial segregation of a binary mixture of grains in a rotating drum is studied using Molecular Dynamics (MD) simulations. A force scheme leading to a constant restitution coefficien…
