Abstract

Dry granular flows in half-filled horizontal rotating cylinders were studied by NMR to ascertain end-wall effects. The velocity at the end-wall of a long. i.e., 3D, cylinder is slower than at the axial center for all depths. For 2D geometry, the velocity at the free surface is faster but slower deep down in the flowing layer than in the center of a long cylinder. We conclude that the velocity profile at the end-wall, either of a 2D or 3D cylinder, is different from the profile far from the end-wall in a 3D cylinder but for different reasons.
