Abstract

The burning velocity of premixed carbon monoxide-nitrous oxide flames (background water levels of 5 to 15 ppm) has been determined experimentally for a range of fuel-oxidizer equivalence ratio phi from 0.6 to 3.2, with added nitrogen up to a mole fraction of XN2 = 0.25, and with hydrogen added up to XH2 = 0.005. Numerical modeling of the flames based on a recently developed kinetic mechanism predicts the burning velocity reasonably well, and indicates that the direct reaction of CO with N20 is the most important reaction for CO and N20 consumption for values of XH2
