Measurement and modeling of shock-tube ignition delay for propene

Abstract

Propene ignition was studied behind reflected shock waves at postshock temperatures 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 from 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 τ(s) = 4.2 × 10-15 [C3H6]0.378[O2]-1.043 exp(48800/RT5) for mol/cm3 and cal units was derived. The data could be accounted for using a reaction mechanism with 463 elementary reactions. © 2001 by The Combustion Institute.
