PhD Title: Microwave Resonators for Cryogenic Hydrogen Property Measurement
Guinevere’s research focuses on the development of a novel sensor for the measurement of quantum properties of hydrogen at conditions relevant for hydrogen liquefaction. The sensor is based on the principle of a microwave resonant cavity that utilises the dielectric properties of a contained fluid to determine density and even spin-isomer (ortho-para) hydrogen composition. The new sensor is intended for eventual use in real-time hydrogen liquefaction plant operation where it will be able to both monitor and quality assure outputted liquid hydrogen streams. As well as the development of this sensor, Guinevere’s work also includes the measurement of new high accuracy hydrogen property data in order to improve on the current hydrogen equation of state which falls short when predicting hydrogen properties at the low temperature used in liquefaction.
Guinevere graduated from the University of Western Australia (UWA) with a Bachelor of Philosophy (Hons) in Chemical Engineering and Applied Mathematics and has continued her Honours research as a current PhD candidate at UWA as part of the Fluid Science & Resources research group. As well as her coursework, Guinevere has also had previous research experience as a research assistant for the Fluid Science & Resources group working on projects related to hydrogen enriched natural gas.
