2-Methyl-Pentane Ignition Kinetics in a Shock-Tube

Abstract

The ignition of 2-methyl-pentane, was modeled and compared to experiments of ignition delay time in a shock-tube, using n-pentane, 2-methyl-pentane and n-hexane in mixtures with oxygen diluted with argon. The product distribution of the preignited mixtures were also investigated and numerical modeling of the combustion kinetics was performed. The 2-methyl-pentane (2MP) experiments 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 kinetic scheme containing 430 elementary reactions, and then reduced to a scheme containing 110 reactions only.
