Application of NMR to Rotating Granular Flow

Document Type: Proceeding Paper

Part of: Engineering Mechanics

Abstract:

Granular flow in a steadily rotating cylinder, having a large length-to-diameter ratio, is measured by nuclear Magnetic Resonance Imaging (MRI). This non-invasive technique is capable of obtaining three dimensional images of concentrations and velocity profiles of flows of suitable granular materials. We present two-dimensional concentration images of a transverse cross section through the cylinder center for flowing granular particles and for flowing mixture of granular particles-water. We also show how tagged stripes on granular materials can yield information about their motion.
