Abstract

The sparse-Lagrangian MMC-LES approach is applied here, and for the first time, to swirling jets and flames stabilized on the Sydney swirl burner. Non-reacting case N16S159 is firstly simulated to demonstrate the ability to compute the recirculating flow fields. Reacting methane-air case SMA2 is then simulated using the sparse-Lagrangian MMC-LES model with detailed chemistry involving 19 species. Results show good predictions of the flow field including vortex breakdown and the extent of the recirculation zone. The results are sensitive to the specification of turbulence on the boundary. The mixture fraction and temperature fields are in excellent agreement with experimental mean and rms hence validating the applicability of sparse-Lagrangian MMC mixing model to flames with complex flow.
