Hopper flow of nonspherical granular particles — •János Török1, Gábor Szabó2, Ellák Somfai2, and Tamás Börzsönyi21Department of Theoretical Physics, Budapest University of Technology and Economics, H-1111 Budapest, Hungary — 2Institute for Solid State Physics and Optics, Wigner Research Center for Physics,

We present experimental results of hopper flow with spherical and nonspherical granular particles. We show that the flow widens with the increasing hopper flow angle, but shrinks with the increasing particle aspect ratio, where the flow also gets more intermittent with a well defined frequency. The results are compared to a mesoscopic model based on the principle of minimal dissipation. We show that due the the elongated particles the shape of the flow changes and becomes more straight.
