AbstractThe influence of hydrogen enrichment on the topology of lean CH4-H2/air turbulent V-flames was considered. Three equivalence ratios with different levels of hydrogen enrichment were studied for variations in flame topology. The turbulent flame speed and turbulent flame brush thickness both increased with hydrogen enrichment for all flame considered. Flame surface density profiles showed a progressive shift towards the products and curvature PDFs showed a bias towards positive curvatures. Observed trends were attributed to the changes in thermo-diffusive stability of the reactants as Lewis numbers decreased with hydrogen volume fraction.
