Co Time-Histories Measurements Behind Reflected Shockwaves During Ignition Of Various Gaseous Fuels

Abstract

Carbon monoxide time-histories were measured for two common fuels behind reflected shockwaves using laser diagnostics. A CO laser diagnostic scheme was used to measure the absorbance during combustion of methane and ethylene. Experiments were performed for a temperature range between 1100 and 2100 K. The pressure ranged between 1 to 1.8 atm at the low pressures to 7 to 9 atm for the high-pressure experiments. The ignition delay times were also measured during these experiments. All data were compared to predicitons of a detailed kinetic mechanism from the literature. It is observed that the ignition delay times can be predicted for methane combustion but not at low pressures and elevated temperatures for ethylene. Imoprovements to mechanism can be made based on current experimental data.
