A review will be provided of the state-of-the-art in subgrid scale (SGS) modeling as required for large eddy simulation (LES) of turbulent combustion. The closure complexities caused by chemical reactions are the subject of main discussion. The SGS closure based on the stochastic \¯ltered density function" (FDF) method is described in a greater detail. Some of the other closures are reviewed in the context of this method. LES/FDF provides a very a®ordable and reliable means of predicting turbulent reacting °ows. Results will be presented of recent implementation of this technology for simulations of a variety of turbulent °ames.
Biography
Dr. Peyman Givi is the William Kepler Whiteford Professor of Mechanical Engineering and
Materials Science ( at the University of Pittsburgh (Pitt). Previously he held the position of University Distinguished Professor at the State University of New York (SUNY) at Bu®alo where he received the Professor of the Year Award by Tau Beta Pi in 2002. Dr. Givi has also worked as a Research Scientist at the Flow Industries, Inc. in Seattle. He has had frequent visiting appointments at the NASA Langley Research Center and the NASA Glenn (Lewis) Research Center, and received the Agency's Public Service Medal (2005). Professor Givi is amongst the ¯rst 15 engineering faculty nationwide who was honored at the White House to receive the Presidential Faculty Fellowship from President George H.W. Bush (1992). In 1990 he received the Young Investigator Award of the O±ce of Naval Research (ONR), and the Presidential Young Investigator Award of the National Science Foundation (NSF). Dr. Givi is a member of the editorial boards Computers & Fluids (1993-present), Open Aerospace Engineering Journal (2007-present), Journal of Applied Fluid Mechanics (2005-presents); is Associate Editor of AIAA Journal (1998-2009), International Journal of Reacting Systems (2006-present); and a past ad-
visory board member of Progress in Energy and Combustion Science (1996-2004). He received Ph.D. from the Carnegie-Mellon University (PA) in 1984 and BE (Summa Cum Laude) from the Youngstown State University (OH) in 1980, where he was named the 2004 Distinguished Alum- nus by the local Chapter of the Phi Kappa Phi honor society. Dr. Givi is Fellow of the American Physical Society (APS), Fellow of the American Society of Mechanical Engineers (ASME) and Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA). In 2007, ASME named Dr. Givi the \Engineer of the Year" in Pittsburgh.
