Non-invasive measurements of granular flows by magnetic resonance imaging
Abstract
Magnetic resonance imaging (MRI) is used to non-invasively measure concentration and velocity fields of flows of granular materials in the rolling mode in a half-filled horizontal cylinder rotating at various speeds. We report that the thickness of flowing layer, defined as the flow thickness of the region where particles are in relative shear with respect to the packed particles that are in rigid body motion, monotonically increases with the rotation rate. In addition, the velocity profile near the free surface is not symmetric around the center of the cylinder.
