Title

Effect Of Silane Addition On Acetylene Ignition Behind Reflected Shock Waves

Abstract

Ignition delay time and species profile measurements were reported for the combustion of C2H2/O2/Ar mixtures with and without the addition of silane at 1040-2320 K and near 1 atm. For the cases without silane, there was good agreement between the present data and some recent acetylene oxidation results. Small SiH4 additions (< 10% of the fuel) reduced the ignition time in stoichiometric mixtures by as much as 75% for shocks near 1800 K. Similar reductions were seen in the fuel-lean mixture, although the effect was less temperature dependent. Several detailed chemical kinetics mechanisms of hydrocarbon oxidation were compared to the ignition delay time data and species profiles for C2H2/O2/Ar mixtures without silane. All models under-predicted ignition time for the 98% diluted stoichiometric mixtures but matched the fuel-lean ignition data somewhat better. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
