Abstract (may include machine translation)

Two-dimensional hydrodynamic lattice gas cellular automata have been generalized to the cases when the collisions are inelastic and there is friction between the particles. These models can be used successfully to describe various features of granular media. Here we briefly describe results on avalanche statistics and the filling of a silo with mono-disperse grains and a binary mixture. In the former case we have found good qualitative agreement with the IBM experiment [1] showing scaling for small piles but none above a critical size. The steady state profile during the filling of the silo seems to be well described by the recent Boutreux-de Gennes [2] theory. The agreement with the theory for binary mixture is also good though deviations due to inertia effects occur.
