Armin Wehrfritz obtained his Master's degree in mechanical engineering from the University of Kaiserslautern, Germany, and his doctoral degree from Aalto University, Finland. During his doctoral studies, he was a visiting researcher in the Combustion Technology group at Eindhoven University of Technology, The Netherlands. For his postdoctoral research, he moved to Sydney, Australia, where he held an appointment as Research Associate at The University of New South Wales.
Armin’s primary research interests are in high-fidelity numerical simulations of multiphase and chemically reacting flows, in particular with a focus on low- or zero-carbon fuels such as hydrogen. Aside from his research in energy technology, he has an interest in numerical and computational methods for high-performance computation, as well as data-driven and machine learning methods.
