Methane Ignition Delay Times In Co2 Diluted Mixtures In A Shock Tube

Abstract

This paper presents ignition delay times of methane oxidation diluted with carbon dioxide and argon. The ignition delay times were measured behind reflected shockwaves. The ignition delay times were based on the rise of CH* emissions. Three mixtures were examined by changing the carbon dioxide percentage between 0%, 30% and 60%. Experiments were performed with a constant equivalence ratio of 1 using 3.5% methane and 7.0% oxygen. Temperatures for the experiments ranged between 1600 K to 2000 K for pressures around 1 atm. Experiments were compared to the current state-of-the-art mechanisms. It is shown that the ignition delay times decreased with increasing CO2 amounts in the mixture and the mechanism were able to predict this trend reasonably well.
