This brief communication presents results from a sparse Lagrangian particle method coupled with large eddy simulations (LES) called MMC-LES. It is considered an addendum of an earlier DNS-based study of a syngas shear layer configuration [10] and verifies the enhanced predictive capabilities of a new MMC time scale model. The MMC-LES further demonstrate the correct scaling of the mixing time, the time scale's independence of the filter scale of the underlying LES field and a desirable low sensitivity of the predictions to variations in the primary modelling parameter f(m).
