Abstract
We study experimentally the jamming phenomenon of granular flow of monodisperse disks of diameter in a two-dimensional hopper with opening . The jamming probability is measured where . We found that decreases from 1 to zero when 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.
