Dissipative properties and scaling law for a layer of granular material ona vibrating plate - art. no. 031304

The dissipative properties and scaling law for a layer of vertically vibrat ed granular materials were investigated by means of a dynamical model of a single sphere colliding completely inelastically with a massive, oscillatin g plate. A relationship is presented of how the temperature of the layer sc ales with the acceleration of the plate and the restitution coefficient of the grains. The numerical calculation shows the existence of an "energy wel l" and a "temperature well," which could be used to explain the existence o f a f/2 flat (where f is the external driving frequency) state in an experi ment on vibrated granular material.
