摘要: Abstract This study presents new ignition delay data measured in a rapid compression machine over wide range temperature, pressure and fuel/air ratio. is an extension of that previously (D. Darcy, C.J. Tobin, K. Yasunaga, J.M. Simmie, J. Wurmel, T. Niass, O. Mathieu, S.S. Ahmed, C.K. Westbrook, H.J. Curran, Combust. Flame, 159 (2012) 2219–2232.) for the oxidation n-propylbenzene high-pressure shock tube. The was obtained equivalence ratios 0.29, 0.48, 0.96, 1.92, at compressed gas pressures 10, 30 50 atm, temperature 650–1000 K. Experimental also 50 atm all our heated tube this presented here. Comparisons between both facilities showed excellent agreement. A published chemical kinetic mechanism has been improved low-temperature reaction added to simulate times lower conditions by adding appropriate species reactions including alkyl-peroxyl hydroperoxy-alkyl radical chemistry. Special attention given R O 2 isomerizations H elimination involving secondary benzylic site on obtain good agreement with present experimental results. In general, model experiments consistent trends were observed these are discussed.
