Modeling Ozone Decomposition Flames

An updated detailed kinetic mechanism for ozone combustion is developed. The contemporary choice of the reaction rate constants is presented with emphasis on their uncertainties. Model predictions are compared with available experimental data for ozone decomposition flames and with the Moscow State University (MSU) mechanism used elsewhere in the literature. These two models show similar performance in calculating laminar burning velocities, yet predict largely different concentration profiles of singlet oxygen, O-2(a(1)triangle g). The necessity for consideration of all reactions included in the mechanism as reversible is emphasized.
