Abstract

Ignition time measurements of lean, stoichiometric, and rich n-heptane/oxygen/argon mixtures have been studied behind reflected shock waves in the temperature range 1300-1600 K and pressure range 2-4 atm. The experimental data were compared to previously published results and have been found to be consistent with them. The experimental data were compared to ignition delay predicted using some of the kinetic models available in the literature. Discrepancies have been interpreted kinetically, thus leading to a slightly modified detailed kinetic model able to predict accurately high-temperature ignition delay such as encountered in the heptane/oxygen detonation wave.
