  Recent advances in the high performance computing have enabled first principle simulations of laminar and turbulent reacting flows to unravel fine-scale physics with ultimate realism and accuracy. To achieve this mission successfully, however, it is essential to develop reliable algorithms that are free from turbulence modeling errors and numerical dissipation. Furthermore, the implemented submodels should be able to describe the essential physical and chemical processes, such as radiative heat transfer, spray dynamics, and soot formation. This presentation will provide an overview of recent research activities using direct numerical simulations (DNS) with detailed chemistry and transport. In particular, DNS of auto-ignition in the presence of mixture stratification is analyzed to provide insights into the characterization of auto-ignition regimes and as a means to develop improved mixing models for turbulent combustion simulations. The presentation will also provide a brief overview of ongoing activities and research opportunities at KAUST Clean Combustion Research Center.

  Hong G. Im received his B.S. and M.S. in Mechanical Engineering from Seoul National University, and Ph.D. in Mechanical and Aerospace Engineering from Princeton University.  He spent two years as a Research Fellow at the Center for Turbulence Research, Stanford University, followed by a post-doctoral tenure at the Combustion Research Facility, Sandia National Laboratories. He joined the University of Michigan in 2000 in the Department of Mechanical Engineering, where he currently holds a Professor position. He recently joined KAUST as a Professor of Mechanical Engineering and Clean Combustion Research Center, while taking a leave of absence from the University of Michigan.
  Hong Im’s research and teaching interests are primarily fundamental and practical aspects of combustion and power generation devices using high-fidelity computational modeling.  Recent research topics include modeling of combustion in low temperature combustion engines, advanced models for turbulent sooting flames, and combustion characteristics of high hydrogen content fuels for advanced gas turbine applications. He is a recipient of the NSF CAREER Award and SAE Ralph R. Teetor Educational Award. He is an Associate Fellow of American Institute of Aeronautics and Astronautics (AIAA) and a Fellow of American Society of Mechanical Engineers (ASME). He has also served as an Associate Editor for the Proceedings of the Combustion Institute.
