A Combined Level-Set/Mixture Fraction/Progress-Variable Approach for Partially-Premixed Turbulent Reacting Flows

*† ‡ § An approach to predict partially-premixed turbulent reacting flows is presented in this paper within the context of large-eddy simulation (LES). A high-order, fully compressible LES flow solver is combined with a level-set/mixture fraction flamelet formulation to predict combustion in premixed and partially-premixed turbulent reacting flows. The results for a lean premixed dump combustor are compared with available experimental results and previous numerical studies. A good agreement between the numerical results and the experimental data is observed. Future validation will include comparisons with experimental data obtained in realistic engineering configurations such as augmentors.
