Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame

From Large-Eddy Simulation to Direct Numerical Simulation of a lean premixed swirl flame: Filtered laminar flame-PDF modeling

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.

A two-step chemical scheme for kerosene–air premixed flames

Large-eddy simulation of a fuel-lean premixed turbulent swirl-burner

Large-eddy simulation (LES) of an igniting turbulent hydrogen/air jet for which experimental data are available is reported. A sub-grid scale closure is proposed that is based on a tabulation of detailed chemistry combined with a presumed probability density function, to be implemented into a fully compressible LES solver. The simulations are performed in a frame moving with the mean flow. The obtained results are shown to reproduce the experimental findings in terms of ignition length. A dynamic closure is used for the unknown sub-grid scale (SGS) scalar dissipation rate of mixture fraction and the sensitivity of the chemical response to SGS modelling is studied.
