Abstract

Large-eddy simulations (LES) of non-premixed hydrogen impinging flames using different chemical kinetics have been performed in this study. The work is mainly focused on the formation of vortical structures in the primary and wall jets, along with the analysis of heat transfer. The configuration corresponds to a laboratory hydrogen jet flame issuing from a circular nozzle which impinges on a downstream wall with a nozzle to plate distance of H/D = 20. The numerical simulations were performed using the same subgrid scale model but different finite-rate chemical kinetic mechanisms. The results show appreciable differences in the predictions of vortex formation and near-wall heat transfer due to the influence of the chemical reactions on the flow field.
