Abstract: In this paper, we review the recent progress in dynamic Subgrid-Scale (SGS)
Heat-Flux (HF) modelling for Large-Eddy Simulation (LES) of turbulent thermal
convection. A general framework applied towards the development of advanced explicit
algebraic dynamic tensor diffusivity SGS HF models will be provided. Most of the currently
available explicit algebraic SGS HF models based on a symmetrical tensor diffusivity can be
derived using this general framework for modelling. An application of the derived SGS HF
models will be illustrated with results from numerical simulations of thermal convection in
vertical, horizonal, and rotating channels.
Keywords: turbulence; heat transfer; convection; LES; large-eddy simulation; subgrid-scale
model.

Biographical notes: Bing-Chen Wang has been an Assistant Professor in the Department of
Mechanical and Manufacturing Engineering at the University of Manitoba since 2008. After
receiving his PhD Degree from the University of Saskatchewan in 2004, he was awarded
a NSERC Visiting Fellowship to conduct postdoctoral research at Defence Research &
Development Canada, in Suffield, Alberta. After completing his three-year postdoctoral
program, he was appointed as a Defence Scientist with Defence R&D Canada – Suffield
one year before he joined the University of Manitoba. His current research interests include
large-eddy simulation, hybrid RANS/LES, environmental flow and dispersion, turbulence
modelling, convective heat and mass transfer, and high-performance scientific computing.
Qian-Qiu Xun is a PhD candidate in the Department of Mechanical and Manufacturing
Engineering at the University of Manitoba. He obtained his BSc Degree in Environmental
Engineering from Xian Jiaotong University in 2007, and obtained his MSc Degree in
Mechanical Engineering at the University of Manitoba in 2009.
