About the Presenters:

Professor Richard Morgan

Richard Morgan came to Brisbane in 1980 to work on Australia’s first Scramjet project with Pioneering Professor Ray Stalker, the founder of the UQ Hypersonics group.

Since that time he has worked actively in hypervelocity ground facility development in the form of expansion tubes and shock tubes, and on a range of topics in high speed aerothermodynamics. He initiated the ‘Mechanical and Space Degree’ in 1994, which subsequently transformed to the ‘Mechanical and Aerospace’ degree currently offered at UQ. He was the founding Director of UQ’s Centre for Hypersonics in 1997 and served in that role until October 2021.

Associate Professor Stuart Laurence

Stuart Laurence is currently an Associate Professor in the Department of Aerospace Engineering at the University of Maryland (UMD). He received his Ph.D. from the Graduate Aeronautical Laboratories of the California Institute of Technology in 2006. From 2009, he was employed as a scientific researcher at the German Aerospace Center (DLR), Goettingen, before joining the faculty at UMD in 2013. His research interests, which are primarily experimental in nature, encompass a range of problems within the general area of high-speed flows, including boundary-layer transition to turbulence, shock-wave/boundary-layer interactions, fluid-structure interactions, multi-body separation, supersonic combustion, and high-altitude flow measurements. A particular focus of his work is the use of high-speed visualization techniques to enhance our understanding of these problems.

Dr Marianne Omang

Dr Marianne Omang is a senior researcher working for the Norwegian Defence Estate Agency (NDEA) in their R&D Section. In 2005 Dr Omang completed her PhD from the Institute of Theoretical Astrophysics (ITA) at the University of Oslo. Dr Omang also has a part time position as an Associate Professor at ITA.

In the last years the focus of Dr Omang’s work has been on multi-phase problems including shock interaction with inert and reactive particles. Together with her colleagues she has spent quite some time on planning and building up a Laboratory facility for studies of shock and blast waves. A wide range of different experiments are performed here, including phenomena related to ignition and burning of reactive particles both in a shock tube environment as well as in additives of high explosives.

The experimental work is supplemented by numerical simulations using their in-house code Regularized Smoothed Particle Hydrodynamics (RSPH). They have recently extended our code to include a multiphase description and various particle combustion models.
