Jamming of Granular Flow in a Two-Dimensional Hopper (original) (raw)

Abstract

We study experimentally the jamming phenomenon of granular flow of monodisperse disks of D=5mm diameter in a two-dimensional hopper with opening R. The jamming probability J(d) is measured where d≡R/D. We found that J(d) decreases from 1 to zero when d increases from 2 to 5. From observing the disk configurations of the arch in the jamming events, the jamming probability can be explained quantitatively by treating the arch as the trajectory of a restricted random walker.
