Abstract:

An overview is presented of recent developments and contributions in large eddy simulation LES of turbulent reactive flows. The foundation of some of the recently proposed subgrid scale SGS closures for such simulations is presented, along with a discussion of their capabilities and limitations. The scope of the review is limited to physical modeling. In doing so, only issues pertaining to additional complexities caused by chemical reactions are discussed. That is, the challenges associated with general LES of non-reactive flows are not considered, even though all of these diallenges are indeed present and in most cases are a lot more complex in reactive flows. It is recognized that numerical algorithms and computational procedures play a significant role in any LES. However, this review does not deal with these issues except for cases wherein the actual numerical-computational methodology is directly coupled with the procedure by which LES is conducted. The SGS closure based on the recently developed filtered density function FDF method is described in a greater detail. This is due to more familiarity of this reviewer with this closure it does not imply that other closures are less effective.
