Abstract:

The burning of fossil fuels in practical combustion devices predominantly involves turbulent flows. Combustion in turbulent flows can be characterized as multiscale and multiphysics phenomena. When burning typical hydrocarbon fuels, tens or hundreds of species are involved, and the rates of combustion and pollutant formation reactions are substantially influenced by non-linear interactions with multiscale fluid turbulence. With increasing computational power, a predictive model for turbulent combustion is expected to play an increasingly important role in improving fuel efficiency and mitigating pollutant emissions of combustion devices. In this talk, recent progress and challenges in the modeling of turbulent combustion are discussed. The scope of the talk will be restricted to the non-premixed mode of combustion, burning either gaseous or liquid fuels. After discussing the major challenges and briefly reviewing combustion models of major interest, the talk will focus on the progress made in the Computational Combustion and Energy group.

Bio:

Seung Hyun Kim is an Assistant Professor in the Department of Mechanical and Aerospace Engineering at The Ohio State University. He received B.S., M.S., and Ph.D. degrees from Pohang University of Science and Technology, Korea, in 1996, 1998, and 2003, respectively. Before joining OSU, he worked as an Assistant Professor at Michigan Technological University, and a Research Associate and a Postdoctoral Fellow at Stanford University. His research interests focus on computational modeling of reacting flows in energy and propulsion systems.
