2-methyl-pentane ignition kinetics in a shock-tube

The ignition of 2-methyl-pentane, was modeled and compared to experiments o f ignition delay time in a shock-tube, using n-pentane, 2-methyl-pentane an d n-hexane in mixtures with oxygen diluted with argon. The product distribu tion of the preignited mixtures were also investigated and numerical modeli ng of the combustion kinetics was performed. The 2-methyl-pentane (2MP) exp eriments were run at temperatures of 1175 to 1772 K and pressures of 2 to 4 .6 atmospheres. The numerical modeling of 2MP was performed with a large ki netic scheme containing 430 elementary reactions, and then reduced to a sch eme containing 110 reactions only.
