Introduction,s must at the very least be visible to the naked eye. This is in contrast to mesoscopic or microscopic media. As it turns out, the very concept of granular material imposes some further restrictions, raising the low end of the range somewhat above the limits of our visual acuity. It is important to

Interactions in Granular Media,sually air) or in a liquid. The properties of granulars depend primarily on the nature of the interactions between the particles themselves, but also between the particles and their environment. When the influence of the environment can be neglected, we deal with what is called . Otherwise, the resu

Granular Media in a State of Flow,ompacted, and that it can be the seat of convection rolls and fragmentation processes. We came to appreciate the crucial role played by the container walls in transmitting collisions to the interior of the material and in activating friction forces. The present chapter is devoted to the dynamic prop

Numerical Simulations,rs, have a twofold objective.. On the one hand, there are pressing incentives to solve a number of practical problems related to the treatment of granular matter in industry. Whether the issue is pesky segregation, blockages of flows by arch effects, or disruptive internal convection phenomena (see
