Guan Heng Yeoh is a professor at the School of Mechanical and Manufacturing Engineering, UNSW, and a principal research scientist at ANSTO. He received his BEng in Mechanical Engineering from the University of New South Wales, Sydney, in 1988 and his Ph.D. in Mechanical Engineering (Computational Fluid Dynamics) from the University of New South Wales, Sydney, in 1993. He is the founder and editor of the Journal of Computational Multiphase Flows and the group leader of Computational Thermal-Hydraulics of OPAL Research Reactor, ANSTO. His research interests are computational fluid dynamics (CFD); numerical heat and mass transfer; turbulence modeling using Reynolds averaging and large eddy simulation; combustion, radiation heat transfer, soot formation and oxidation, and solid pyrolysis in fire engineering; fundamental studies in multiphase flows: free surface, gas-particle, liquid–solid (blood flow and nanoparticles), and gas–liquid (bubbly, slug/cap, churn-turbulent, and subcooled nucleate boiling flows); and computational modeling of industrial systems of single-phase and multiphase flows.
