Abstract

The objective of the current study is to combine a high-fidelity large eddy simulation (LES) flow solver with a level-set flamelet algorithm for the prediction of premixed turbulent combustion. The same level of high accuracy is implemented for simulation at all speeds. The goal of this work is to accurately predict the unsteady turbulence-flame interaction for realistic industrial combustors with complex geometries. The numerical issues related to the numerical implementation of the LES equations, flamelet model and level-set algorithm are presented in detail. The accuracy of the numerical implementation is verified through comparisons with experimental data for an augmentor flame holder and a turbulent Bunsen burner flame.
