Rate My Professor Geoffrey Evans

Professor Geoffrey Evans is an Honorary Professor in the Discipline of Chemical Engineering within the School of Engineering, College of Engineering, Science and Environment, at the University of Newcastle, Australia. He holds a PhD and a Bachelor of Engineering (Honours) from the University of Newcastle. For more than 30 years, he has been actively involved in fundamental and applied research into multiphase systems, focusing on free surface phenomena and phase interactions between bubbles, particles, droplets, liquids, and gases. His research includes bubble formation, growth, nucleation, breakup, coalescence, two-phase flow, mixing, agitation, emulsions, plunging and submerged jets, surface forces, particle-particle and bubble-particle interactions, and particle technology applications in fluidized beds, bubble columns, and flotation cells. He employs techniques such as high-speed particle image velocimetry, thermal imaging, computational fluid dynamics, direct numerical simulation, and discrete element modeling. Applications encompass sustainable water and wastewater treatment, mineral processing and beneficiation (40% focus), powder and particle technology (60% focus), pyro-metallurgical processing, process industries, fluid mechanics, interfacial phenomena, flotation processes, and fluidization.

Evans has held significant roles including Head of the Department of Chemical Engineering (1999-2001), Assistant Dean of Research and Graduate Studies, Chairman of the Faculty Research Committee and Higher Degrees Committee, and Assistant Dean for Community Relations and Marketing at the University of Newcastle. He served as Research Associate at the University of Cambridge Department of Chemical Engineering and has been Managing Director of the Priority Research Centre for Advanced Particle Processing and Transport since 2010. He participates in ARC centres such as the Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals (2020-2026) and Research Hubs for Australian Steel Innovation (2020-2024) and Advanced Technologies for Australian Iron Ore (2013-2018). An elected Fellow of Engineers Australia and the Institution of Chemical Engineers (UK), he has been on the Editorial Board of Elsevier Publishers since 2008. Awards include the CSIRO External Medal for Research Achievement (1990, Jameson flotation cell team), John A. Brodie Medal (2004, best paper), and Best Paper Award (2014, Multiphase Flow). With 8,816 citations, key publications are 'Effect of turbulence dispersion on bubble-particle collision efficiency' (Minerals Engineering, 2022), 'A review of bubble surface loading and its effect on bubble dynamics' (2023), and 'A 2D Numerical Modeling Study of Slag Splashing in a Basic Oxygen Steelmaking Furnace' (ACS Engineering Au, 2025).
