A Shock Tube Study of the Ignition of Mixtures of N2O, CO, and N2

Abstract

A shock tube was employed to determine the ignition limit curves of three mixtures of N2O, CO, and N2. The ignition limit curve, which separates the ignition and no-ignition zones, is an experimentally determined curve plotted on temperature-pressure coordinates. The test gas mixtures of N2O, CO, N2 were ignited by the temperature rise behind the reflected shock wave for pressures in the range of 5 to 65 atmospheres. A 2-inch inside diameter constant area shock tube employing a helium driver was used to generate this reflected shock wave. Limited results were obtained on ignition delay time for each of the three gas mixtures. (Modified author abstract)
