Abstract

Although nitrous oxide has been identified as an important intermediate during the combustion of many solid propellants, there is a limited amount of data concerning the high-temperature oxidation of hydrocarbons by nitrous oxide. In the present study, ignition delay-times of small hydrocarbon–N_2O mixtures with and without O_2 were investigated through shock-tube experiments and chemical kinetic simulations. Experimentally, it is shown that the addition of oxygen induces a significant reduction of the activation energy of the ignition process. Simulations demonstrate that delay-times are usually satisfactorilly predicted but that the detailed reaction models used do not capture all the features of the OH* emission profiles.
