    Arching is studied experimentally and theoretically in a quasi two dimensional system. A model based on a stochastic coupled map lattice is proposed to characterize arching in a vertical and planar stack of similar beads. ...

    Avalanches in a two-dimensional dry granular system, the rotating drum setup, are studied in detail. The distribution of angles at which avalanches initiate and terminate, as well as those for time between avalanches, are ...

    The Jeffery-Hamel flow is analyzed by making use of a mechanical analogy. The solutions are generated by a finite element method, for the corresponding least action principle and are valid for any width of the channel. ...

    Segregation in rotating drums is studied experimentally in two and three dimensions with unexpected results. In the first case, we find that the spatial grain distribution oscillates between uniform and segregated states ...
  • Morales, E; PeraltaFabi, R; RomeroRochin, V (1996)
    We study a cellular automaton that presents a behavior similar to that of avalanches in sand piles. The size distribution of these events presents a clear separation between small and large avalanches
