Characterization of two-phase granular systems using Magnetic Resonance Imaging
The primary objective of this PhD project is to apply ultra-fast Magnetic Resonance Imaging to single- and two-phase granular systems (e.g. suspension or fluidized beds) to elucidate the underlying physics of a number of poorly understood phenomena.
Keywords: Magnetic resonance imgaging
Granular systems are ubiquitous in nature (e.g. rock avalanches or dunes) and of
fundamental importance to industry. However, despite their widespread use and occurrence, many
important phenomena, such as segregation, surface instabilities or formation and coalescence of
bubbles, are poorly understood. This lack of understanding can largely be attributed to difficulties
in acquiring measurements of full 3D granular systems.
Recently, we have advanced Magnetic Resonance Imaging (MRI), in collaboration with Prof.
Prüssmann (D-ITET, ETHZ), to acquire rapid measurements of particle position and velocity [1]. The
primary objective of this PhD project is to apply ultra-fast MRI to single- and two-phase granular
systems (e.g. suspension or fluidized bed) to elucidate the underlying physics of a number of
poorly understood phenomena. In addition, MRI should be advanced to allow ultimately for the
imaging of chemically reactive systems. The ideal candidate shall possess a very good degree of
physics, electrical or mechanical engineering. Previous experience with Magnetic Resonance
Imaging is an advantage, but not a necessity.
