• Ignition delay

Ignition delay times have been measured for gas-phase mixtures of aviation kerosene Jet-A with air at pressures of 10 and 20 atm. The experiments have been carried out in a heated shock tube at a heating temperature of 150 degrees C. The measurements have been performed for the lean, stoichiometric and rich mixtures (phi = 0.5, 1, 2) behind the reflected shock wave in the temperature range of 1040-1380 K. Ignition delay times have been measured using OH* emission at 309 nm and -CH3 absorption at 3.39 mu m. The obtained results are in agreement with the results of other groups. The experimental data have been summarized in a single expression:
tau(ign) = 1.31 x 10(-3) [mu s] . (P/1 [atm])(-0.67) . phi(-0.6) . exp(30.4 [kcal/mol]/RT),
where phi is the equivalence ratio. The measured ignition delay times for Jet-A/air mixtures are given in Annex tables.
