✦ Synopsis

Shock-Tube Studies cm the Ignition of Ethylene-Oxygen-Argon Mixtures Ignition induction times were measured for 9 different ethyietl~~-oxygen-arson mixtures ~4; stokhiometric ratios between 0. I25 and 2. with ethylene mole fractions ranging from O.Ot)25 to 0.02 and total pressures of 3 and 12 atm. The overall correlarion cquatior.i is P = lo-1~-9i~2~4j~.3[02]-1.1[~i~j0.4,34.200/~~ I whera the time, 7, is in seconds and thu concentrstmns are in ~rnoles per cc. Analytical data on quenzhed, partially reacted samples indicate that o.uypn does not participate in the kdti:rting step% wf the reaction. but promotes chain-branchin!: Eteps later cm.
