✦ Synopsis

Shock tube measurements of ignition delay times of propene-oxygen-argon mixtures are presented. The concentrations are varied from 0.6 to 1.6% propene and from 2.7 to 14.4% oxygen diluted in argon. Temperatures in the range of 1274-1840K are achieved with averaged initial pressures ranging from 50 to 133 Torr. The product distribution is analyzed using a gas chromatograph. The overall ignition delay correlation equation, deduced from over 100 experiments, is given by r=5.3X 10 -14 exp(37,500/RT) [C3H6]0.23[O2]-l.t2[Ar]0 s.

The reaction mechanism for propene-oxygen-argon mixtures is investigated numerically and theresults compared to the experimental data.

The numerical calculations are performed with two integration techniques, LSODE and CHEMEQ, converging on a kinetic scheme that includes 59 reactions and 29 species.

The agreement between the experimental data and the numerical predictions is partial, suggesting that the reaction mechanism is not complete.
