A review of using large-eddy simulation (LES) in computational fluid dynamic stud- ies of internal combustion engines is presented. Background material on turbulence model- ling, LES approaches, specifically for engines, and the expectations of LES results are discussed. The major modelling approaches for turbulence, combustion, scalars, and liquid sprays are discussed. In each of these areas, a taxonomy is presented for the various types of models appropriate for engines. Advantages, disadvantages, and examples of use in the litera- ture are described for the various types of models. Several recent examples of engine studies using LES are discussed. Recommendations and future prospects are included.read more

New insights into large eddy simulation
TL;DR: In this paper, the authors proposed a monotone integrated large eddy simulation approach, which incorporates a form of turbulence modeling applicable when the large-scale flows of interest are intrinsically time dependent, thus throwing common statistical models into question.

Large eddy simulation of a nonpremixed reacting jet: Application and assessment of subgrid-scale combustion models
TL;DR: In this paper, the results from large eddy simulations (LES) and direct numerical simulations (DNS) of a two-dimensional, spatially developing, compressible planar free jet undergoing an idealized, exothermic, chemical reaction of the type F+rOx→(1+r)P are presented in order to assess several subgrid-scale combustion models.

Stratified turbulent flames: Recent advances in understanding the influence of mixture inhomogeneities on premixed combustion and modeling challenges
TL;DR: In this paper, the authors introduce experimental facilities and numerical tools applied to investigating inhomogeneously premixed flames, and summarize recent progress in revealing and understanding local phenomena (e.g., back-supported combustion or generation of flame surface area) that stem from the influence of mixture inhomogenities on flame propagation through flammable reactants.
