In this study, combustion mechanisms and effects of flame stretch on the burning velocity of two-component fuel mixtures of hydrogen and hydrocarbon are investigated by chemical kinetics computations. Lean and rich Mixtures having nearly the same laminar burning velocity S(L0) are prepared by adding nitrogen to two-component fuel mixtures where the hydrogen additional rate δ and S(L0) are varied from 0 to 1 and 15 to 35cm/s, respectively. As a result, it is elucidated that Markstein numbers of lean flames are changed monotonically from the value of the hydrocarbon flame to that of the hydrogen flame with increasing δ, however, those of rich flames show a complicated trend. These phenomena are explained qualitatively in light of the production rate of OH and HO(2).
