Strong Shock Waves

Emission spectra excited in various gases, including fuel and fuel+argon mixtures, by strong shock waves from a bursting diaphragm are compared with those given by flames and by spark-ignited and shock-ignited detonations. Shocks through hydrocarbon or hydrocarbon+argon mixtures, without oxygen, give carbon formation and C 2 emission but not CH. Formaldehyde, ether, alcohols, ethyl nitrate, carbon tetrachloride and chloroform have also been studied. Carbon monoxide+argon mixtures give strong C 2 but no CO bands; hydrogen or oxygen only slightly quench this C2, but mixed hydrogen and oxygen quench it strongly. Reactions involving C 2 and CH are discussed. In detonations, OH is very strong, and C 2 and CH are weak compared with burner flames. Time records, using a photomultiplier and oscillograph, indicate that C 2 emission comes from the reaction zone of the detonation, but OH and the continuous spectrum are emitted mainly by the hot gases behind the front. The relation of the results to the propagation mechanism is briefly discussed. Shock-excited spectra resemble those produced by flames rather than those from discharge tubes, and this appears to be a promising technique for studying fundamental processes in flames.

Infrared chemiluminescence attributed to the first overtone of CO was observed when either C2H2 or was introduced into a stream of oxygen which had been passed through a microwave discharge. The addition of vibrationally cold CO to these systems was found to produce a vibrational population inversion in the chemically formed CO. CO first overtone emission was not observed when CH4 was introduced into a similar stream of oxygen unless the CH4 had been subjected to a microwave discharge. These observations are used to clarify the mechanisms governing the formation of CO in continuous wave air–helium–hydrocarbon electrical discharge lasers.
