The Addition Effect of on Methane Ignition behind Reflected Shock Waves


Abstract

The addition effect of $CH^3Br$ on the ignition of methane was investigated in the temperature range of 1537-1920 K behind reflected shock waves. The ignition delay times were measured by the sudden increase of pres-sure and OH emission in the $CH_4-O_2-Ar$ system containing small amount of $CH_3Br.$ The delay times of mix-tures with $CH_3Br$ were shorter than those without $CH_3Br.$ The promotion of ignition by $CH_3Br$ was caused by the relative fast decomposition rate in additive. To clarify the addition effect of $CH_3Br$ from the viewpoint of the reaction mechanism, computational analyses were performed in $CH_4-CH_3Br-O_2-Ar$ mixtures.
