Application of Magnetic Resonance Imaging techniques to particulate systems

摘要

Magnetic Resonance Imaging (MRI) is a well established technique in the medicalfield typically for imaging liquid water in the human body, but it is increasingly beingused in the field of engineering and materials science. A particular section of this is inthe area of particulate systems and granular material flows. MRI is being used toprovide a unique insight into particle distribution and motion with in-situmeasurements. In this paper we discuss how judicious choice and development ofimaging technique applied to various different granular systems can provide us withvaluable new data on the processes occurring in granular flows. Results are focusedon rotating kiln segregation with some discussion on techniques used in fluidised bedimaging.
