Samuel Harris is a PhD student in the School of Electrical and Mechanical Engineering at the University of Adelaide, focusing on steam-diluted hydrogen combustion to support heavy industry decarbonisation. Replacing the nitrogen in air with steam prevents the production of harmful nitrous oxides from high-temperature hydrogen flames. Steam also allows for temperature control with hydrogen flames, enabling hydrogen to replace fossil fuels. Samuel's research aims to characterise the fundamental behaviour of hydrogen flames in oxygen-steam. The results of this research can lead to future computational fluid dynamics (CFD) modelling work, enabling the design of practical burners and unit operations using steam-diluted hydrogen flames. In addition to decarbonisation, hydrogen combustion aids steam recovery from alumina calcination (as steam is the only product) and aids in iron oxide reduction if the smelter operates in a hydrogen-rich atmosphere. Samuel holds a bachelor’s degree in chemical engineering, majoring in renewable energy, also from the University of Adelaide.
