Using supercomputers to understand fundamentals of turbulent combustion

Prof. Evatt Hawkes, University of New South Wales (UNSW)

“Achieving significant improvements of fuel efficiency and reductions of emissions (including CO2) requires better understanding of the multi-physics turbulent flows that govern the performance of combustors. Direct numerical simulations (DNSs) have long been used to obtain this understanding, but until recently they were limited to very idealised scenarios. Advances in supercomputing have enabled rapid progress, such that DNSs of laboratory-scale experiments are now possible. In this article I will discuss recent examples of DNS performed in my group at the University of New South Wales, focussing on the stabilisation of lifted flames and on flame structure in high Karlovitz number lean premixed flames.”

Personal bio of Prof Evatt Hawkes

Evatt Hawkes is a Professor in the School of Mechanical and Manufacturing Engineering at the University of New South Wales (UNSW). Prior to joining UNSW, he received his PhD from the University of Cambridge and then undertook post-doctoral research at the Combustion Research Facility at Sandia National Laboratories. His research centres on the application of high-fidelity simulation techniques to the turbulent reacting flows that govern the performance of emissions of energy devices. His group is known for pushing the envelope of what is possible using large scale supercomputing resources to advance understanding of combustion and to help develop practically useful combustion models. He serves as Editor for Flow, Turbulence and Combustion, and is a colloquium co-chair for the 36th International Symposium on Combustion.
