We report results concerning the dynamical behavior of collections of beaded chains rotated in a two dimensional cylinder. During our experiments, we observe a variety of complex spatio-temporal patterns. These patterns depend on the chain length, the size of the system, and the rotation rate of the cylinder. We report the porosity of the granular chains under flow, the conformation of chains, and the end-to-end distance of chains in comparison to the polymer melt system.
