Abstract

Preferential diffusion effects are investigated in flame stabilization of turbulent lifted flames using LES with a FGMPDF model. The experimental test case is the Delft JHC burner in which methane based fuel has been enriched with various amounts of H2. A novel numerical model is proposed based on the Flamelet Generated Manifolds (FGM) to account for preferential diffusion effects in autoignition. Afterwards, this model is implemented in LES of the H2 enriched turbulent lifted flames. Main features of these turbulent lifted flames such as the formation of ignition kernels and stabilization mechanisms are analyzed and compared with the measurements.
