Numerical study of flame stabilization for laminar premixed methane flames with hydrogen addition

Addition of hydrogen in natural gas lowers the emissions. However, the stability of flames with hydrogen addition poses a problem with respect to the lean blow-off limit. For this purpose, it is critical to understand the phenomenon of flame stabilization near the lean blow-off limit. Bluff body stabilized flames present an interesting case study for examining the effects of the hydrogen addition, because of their similarity when compared to the laminar flames encountered in domestic burners.
