Packing, alignment and flow of shape-anisotropic grains in a 3D silo experiment
Granular material flowing through bottlenecks, like the openings of silos, tend to clog and thus inhibit further flow.We study this phenomenon in a three-dimensional hopper for spherical and shape-anisotropic particles by means of x-ray tomography.The x-ray tomograms provide information on the apac1/60/1/cw bulk of the granular filling, and allows
