Researcher biography
Dr Tristan Vanyai's research interests are in the fields of hypersonic propulsion, aerodynamics, combustion visualisation and laser diagnostics, using both experimental and numerical techniques.
Dr Vanyai received his Doctor of Philosophy from The University of Queensland in 2018, after completing a Bachelor of Aerospace Engineering (First Class Honours) and Bachelor of Science double degree at Monash University in 2012.
His research focuses on fundamentals of hypersonic propulsion through the scramjet cycle. Robust combustion within low intake compression scramjets is a key technology enabler for hypersonic accelerator vehicles, and can be achieved through utilising techniques such as thermal compression. Dr Vanyai is examining the improvements to scramjet combustion due to thermal compression through experiments in the T4 Stalker Tube facility using advanced optical techniques and comparison with results from numerical simulations.
