Abstract

A hybrid Euler/Lagrange approach is used to model stratified lean premixed combustion in a turbulent flow. Large eddy simulations (LES) are coupled with an artificially thickened flame (ATF) approach for the computation of the reaction progress variable. This approach is combined with a sparse Lagrangian particle method for the modelling of the inner flame structure. A multiple mapping conditioning (MMC) mixing model is applied to prevent direct mixing across the flame front. Predicted flame structures are compared with measurements of a stratified premixed laboratory flame yielding good agreement and demonstrating the model’s capability to predict relatively thin flames and to approximate a flamelet-like inner flame structure.
