Abstract

This paper presents large eddy simulations (LES) of piloted partially premixed turbulent flames with homogeneous inlets. It is a first attempt to implement Shadow Positions (SP) [1] as reference variable in the MMC-LES modelling framework. The Sydney piloted burner is employed here although, at this stage, without any compositional inhomogeneity at the exit plane. The Shadow Position vector is used as reference variable for conditioning in the mixing model and a flame sheet approximation is made to treat the chemistry. Comparisons between the predictions and the experimental measurements are made. The flame structure is adequately predicted and it serves as a good starting point to expand the use of SP in multiple mapping conditioning (MMC) to compute the structure of premixed flames [2] and hence mixed-mode flames similar to those produced in the Sydney Burner when composition inhomogeneity is introduced.
