Abstract
The ignition of a gas mixture containing 8 mole %H2 and 2 mole %O2 in argon was studied in a shock tube at 960°—1080°K. The observed ignition delays were longer than would be expected by extrapolation of data obtained by other workers at higher temperatures. The rapid increase in induction time with decreasing temperature can be accounted for quantitatively by an ignition mechanism involving HO2 radicals.Keywords
