Measurement and modeling of shock-tube ignition delay for propene

Propene ignition was studied behind reflected shock waves at postshock temp eratures ranging from 1270 to 1820 K and postshock pressures from 0.95 to 4 .7 atm, Reactant concentrations were varied from 0.8 to 3.2% propene and fr om 3.6 to 15.1% oxygen diluted in argon, giving equivalence ratios ranging from 0.5 to 2.0. The pressure-based ignition delay correlation equation tau (s) = 4.2 X 10(-15) [C3H6](0.378)[O-2](-1.043) exp(48800/RTS) for mol/cm(3 ) and cal units was derived. The data could be accounted for using a reacti on mechanism with 463 elementary reactions. (C) 2001 by The Combustion Inst itute.
