Abstract

Magnetic Resonance Imaging (MRI) was used to non-invasively measure velocity and concentration of granular flows in a partially filled, steadily rotating, long, horizontal cylinder. First, rigid body motion of a cylinder filled with granular material was studied to confirm the validity of this method. Then, the density variation and the depth of the flowing layer, where particles collide and dilate, and the flow velocity profile were obtained as a function of the cylinder rotation rate.
