NUMERICAL AND MODELING STRATEGIES FOR THE SIMULATION OF THE CAMBRIDGE STRATIFIED FLAME SERIES
SINOPSIS
The Cambridge stratified swirl burner (SwB) has been experimentally investigated for premixed and stratified flame regimes with non-swirling and swirling injection streams. The choice of an appropriate numerical and modeling strategy to capture both stabilization mechanism and turbulent flame propagation is a challenging issue. The present paper presents a comparison between two different approaches. The first one uses a Flame Surface Density (FSD) approach associated to a structured low-Mach code. The second one uses the Filtered Tabulated Chemistry for Large Eddy Simulation (F-TACLES) model implemented in an unstructured low-Mach code. LES results of the non reactive, fully premixed and stratified non-swirling cases are presented and discussed. A good agreement on velocity, mixing and temperature statistics is found for both approaches.
