    Abstract:
    In some grain systems of practical interest, however, the dispersed grains, although playing an important role in the system dynamics, are not numerous enough to justify a continuum description a priori. We have studied a computer model of one such system, in which a small number of inelastic spheres driven by a localized energy source are confined to an enclosed three dimensional space. Grain inelasticity exerts a dominant influence on these systems. With respect to the Maxwellian velocity distribution which elastic particles with the same average 'temperature' would show, the simulated velocity distribution exhibits a peak at lower energy, with a significant high energy tail.
