New kinetic results for the oxidation of hydrogen in diluted conditions, perturbed by the addition of various concentrations of NO or NO₂ were obtained in a jet-stirred reactor. The experiments were performed over the temperature range 700–1150 K, for pressures of 1 to 10 atm, and equivalence ratios from 0.1 to 2.5. The experiments were performed at fixed residence time, τ, and variable temperature. Sonic probe sampling at low pressure followed by on-line and off-line chemical analyses (gas chromatography and FTIR) were used to follow the reaction. A detailed kinetic modeling of the present experiments was performed using the proposed kinetic scheme. Further validations of this kinetic reaction mechanism were performed simulating the ignition of hydrogen-air and hydrogen-NO_x-air mixtures, and the burning velocities of hydrogen-air mixtures. The present modeling results agreed well with the flame data and the ignition data of H₂-air-NO mixtures but disagree with the mixtures containing NO₂. The present results support the low literature value of the rate constant for the reaction of NO₂ with H₂ whereas a much higher rate constant is needed to fit the ignition delays of the H₂-air-NO₂ mixtures.
