abstract
Shock-tube experiments have been performed to determine ignition delay times of undiluted ethylene-air mixtures over a wide range of temperatures (1003 T (K) 1401), stoichiometries (0.5 2.0), and pressures (1.1 P (atm) 24.9). The results of this work are compared to other experimental data available in the literature and to a chemical kinetics model that has been developed over the past few years using high-pressure, lower order hydrocarbon ignition delay times. The present agreement between model and data is fair, and the experiments show good agreement with the only other high-pressure data set available in literature for ethylene.
