Stratified horizontal flow in vertically vibrated granular layers

, : Stratified horizontal flow in vertically vibrated granular layers. Physical Review. E, Statistical, Nonlinear, and Soft Matter Physics 64(1 Pt 1): 011304-011304

A layer of granular material on a vertically vibrating sawtooth-shaped base exhibits horizontal flow whose speed and direction depend on the parameters specifying the system in a complex manner. Discrete-particle simulations reveal that the induced flow rate varies with height within the granular layer and oppositely directed flows can occur at different levels. The behavior of the overall flow is readily understood once this feature is taken into account.
