Oxidation Behind Shock Waves

Abstract
An experimental and analytical study of the oxidation of acetylene and ethylene
behind incident shock waves was carried out over the temperature range 1815-2365
K at reaction pressures between 1.1 and 1.7 atm. The oxidation process was
monitored by measuring radiation from carbon dioxide, carbon monoxide, and the
reaction O + CO -> CO2 + photon. The recorded emission profiles were analyzed
to obtain concentrations for carbon dioxide, carbon monoxide, and the product of
oxygen atom and the carbon monoxide concentrations. On the basis of this data and
induction time data reported in the literature, kinetic models for acetylene and
ethylene oxidation were assembled. The effect of adding other reactions to the
proposed mechanisms is also discussed.
