Measuring Particle Deposition within Fibrous Filter Media by Magnetic Resonance Imaging

摘要

We report first promising results with particulate materials in the micrometer size range suitable for Magnetic Resonance Imaging (MRI) of dust deposition in fibrous filters. Further we describe the experimental set-up for in-situ experiments of fiber structure and dust loading. We also report first results of dust mass distribution imaging obtained with a clogged filter.
