Sarah Razzaqi

Dr. Sarah Razzaqi is an Honorary Fellow at the School of Mechanical and Mining Engineering at The University of Queensland. Her primary research focuses on hypersonics and scramjet propulsion systems, with special expertise in oxygen enrichment techniques for improving scramjet performance.

Dr. Razzaqi's research interests span multiple areas within aerospace engineering:

• Hypersonic propulsion systems, particularly scramjet engines
• Oxygen enrichment techniques for scramjet performance enhancement
• Experimental hypersonic flow characterization
• Freejet and shock tunnel testing of hypersonic vehicles
• HIFiRE (Hypersonic International Flight Research and Experimentation) program
• Computational modeling of hypersonic combustion

Her extensive publication record from 2006-2021 demonstrates a strong focus on experimental and computational approaches to hypersonic propulsion. Dr. Razzaqi has made significant contributions to the understanding of oxygen enrichment in scramjet systems, which has implications for improving the efficiency and performance of hypersonic vehicles. Her work has been integral to the HIFiRE program, an international collaboration between Australia and the United States focused on hypersonic flight research, particularly with the HIFiRE 7 scramjet flowpath testing at Mach 7.5.

Dr. Razzaqi completed her PhD at The University of Queensland in 2011 with a dissertation titled "Oxygen Enrichment in a Hydrogen Fuelled Scramjet." Her early career also included research in phased array ultrasonic transducers and optimization algorithms, demonstrating a multidisciplinary approach to engineering problems that likely informs her current hypersonics research.
