Biographical details

Dr. Agisilaos Kourmatzis is a lecturer in the School of Aerospace, Mechanical and Mechatronic Engineering. His main interests lie in multiphase flows, turbulence, laser diagnostics and energy conversion. He has contributed over 40 publications to this field, of which more than 20 are in peer reviewed journal papers.

Dr. Kourmatzis graduated from the University of Nottingham with a BEng (First Class Hons) in Mechanical Engineering and obtained a MSc (with Distinction), in Advanced Mechanical Engineering, from Imperial College London (2007). He worked as a design engineer at Bombardier Transportation (2007-2008) prior to working towards his PhD in Fluid Dynamics at the University of Southampton, where he graduated in 2011. He was a postdoctoral research associate at the University of Sydney from 2011-2015 and was elected a Chartered Professional Engineer (CEng) with the Institution of Mechanical Engineers in 2014. He held an academic position at Macquarie University from 2015-2017, helping to pioneer the new mechanical engineering program there, prior to re-joining USyd in 2017.

Research interests

While the term itself may be unfamiliar, multiphase flows are all around us, from ocean sprays and aerosol paints to fuel-injected engines and drug inhalers. Dr Agisilaos Kourmatzis’s research into understanding and managing these types of flows has far-reaching implications for our environment, our society and our health.

“A multiphase flow generally consists of a particular phase of matter, such as a liquid droplet or a solid particle, moving or flowing within a different phase, such as a gas.

“My research focuses on developing new and more efficient ways of controlling these types of flows, but also on increasing our understanding of the fundamental science involved, with the overarching goal being to reduce the amount of both energy and material use associated with these flows.

“For example, in a drug inhaler we want to reduce the dose required without negatively affecting the treatment outcome, and in a fuel injector we want to reduce the amount of liquid needed without detrimentally affecting the operation of the engine.

“All of my research comes down to improving efficiency and reducing waste, which not only saves on cost but, more importantly, is much better for our environment.

“The work I’m currently doing with pharmaceutical inhalers and drug delivery is expected to significantly improve our ability to optimise inhaler devices and therefore bring us a step closer to improving treatment outcomes.

“A previous project on fuel sprays has led to one of the world’s largest experimental databases on spray combustion, which is now being used by research groups around the world.

“I’ve been working in this field since around 2008, and first joined the University of Sydney in 2011. There is an outstanding research culture here, enabling high-quality research in my field of interest while in parallel offering multiple exciting interdisciplinary opportunities.”
