摘要：Shock-tube measurements and a kinetic study on the autoignition of hydrogen/n-butane blends were carried out. The Aramco2.0 model was employed in numerical simulation; this model can well capture the autoignitions of the hydrogen/n-butane blends under all test conditions. The pressure dependence, equivalence dependence, and influence of blending of the autoignitions for pure hydrogen, pure n-butane, and the hydrogen/n-butane binary mixture have been studied. A negative pressure dependence of autoignition delay is obtained at the intermediate and low temperatures for the hydrogen and lean XH2 = 98% mixture. The autoignition of n-butane can be nonlinearly enhanced by hydrogen addition. The autoignition of hydrogen was insensitive to the equivalence ratio, but ignitions of the n-butane and binary blends became longer with the rising fuel concentration. The ignition chemistry of hydrogen and n-butane was interpreted.
