Energy Center

Special Combustion Seminar -Graham 'Gus' Nation

August 15 @ 10:30 AM - 11:30 AM - Mechanical Engineering M# 2054

The School of Mechanical Engineering welcomes -Graham 'Gus' Nation the Director, Centre for Energy Technology, The Univesity of Alelaide, Australia. Dr. Nation will speak in the Mechanical Engineering, ME 2054 on August 15, Friday, at 10:30 AM.

Professor Nathan is the founding Director of the University of Adelaide’s Centre for Energy Technology and recipient of an ARC Discovery Outstanding Researcher Award. With more than $20m of research funding, he works with energy technologies spanning the combustion of fossil and bio-fuels, concentrated solar thermal, geothermal energy, wind power, energy storage and in hybrid technologies. He works closely with industry both in developing novel technologies and in identifying and addressing key research challenges, especially those that can be addressed
with advanced laser diagnostics. His past technology developments include being principal leader of the Chief Design Team for the award winning fuel and combustion system for the Sydney 2000 Olympic Relay Torch and joint leadership of the development of low NOx combustion technology in rotary cement kilns. He has published widely, with more than 120 publications in leading journals, 200 in peer-review conferences and 10
patents.

 

Development and Application of Laser Diagnostics to Reveal New Insights into Turbulent Flames with Soot

The seminar will describe recent work at The University of Adelaide in the development and application of laser diagnostics to advance understanding of turbulent flames with soot. A series of planar measurement techniques have been developed, with others under development, to advance capacity to investigate these flames. The use of Two-Line Atomic Fluorescence (TLAF) of Indium is now providing reliable measurement of temperature on the fuel-rich side of the reaction zone, while planar imaging of primary particle size has now also been demonstrated. The presentation will describe these measurement techniques, together with a series of simultaneous investigations of these methods with laser induced incandescence in flames that are carefully designed to also be suitable for model development and validation. Their recent application in the measurement of soot-radiation interactions will also be described under conditions of relevance to concentrating solar thermal hybrid reactors.
