Abstract
In order to clarify and establish a model of the turbulent burning velocity of multi-component fuel mixtures, the turbulent burning velocity of hydrogen added methane-air mixtures with a wide range of equivalence ratio and hydrogen additional rate was examined. The turbulent burning velocity S_T at the same u'/S_<L0> was found to tend to increase with adding hydrogen to methane-air mixtures. The increase of S_T with hydrogen additions in lean mixtures was larger than that in rich mixtures. Additionally, a model of turbulent burning velocity proposed for single-component fuel mixtures may be applied to two-component fuel-air mixtures by considering the estimated mean local burning velocity.
