... in the present study. With hydrogen-enriched fuels, the IRZ expands as LBO is approached, and the attached flame moves inside the IRZ (Figs. 10a 11b ), where turbulence levels are low (Fig. 7 ) and the flame can sustain itself in this low stretch region. Additionally, with the Lewis number being less than...
