PhD Position in Characterization of Two-phase Granular Systems Using Magnetic Resonance Imaging

A fully-funded PhD fellowship in mechanical engineering is available at ETH Zurich. Applications will be evaluated on a continuous basis.

ETH Zurich is one of the world's leading universities specializing in science and technology. It is renowned for its excellent education, its cutting-edge fundamental research and its efforts to put new knowledge and innovations directly into practice. The Laboratory of Energy Science and Engineering in the Department of Mechanical and Process Engineering invite applications for a PhD position in characterization of two-phase granular systems using Magnetic Resonance Imaging

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. Prssmann (D-ITET, ETHZ), to acquire rapid measurements of particle position and velocity (Penn et al., Sci. Adv. 3, e1701879, 2017).

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 an excellent MSc degree in physics, electrical or mechanical engineering. Previous experience with Magnetic Resonance Imaging is an advantage, but not a necessity.
