title = "Influence of water content and its gradient in unburned mixtures on the extinction of a developed detonation",
abstract = "This numerical study investigates different modes of detonation propagation and extinction when a developed detonation pabes through unburned mixtures containing different levels of water content over a specific distance. A time-Accurate, space-Adaptive comprebible reacting flow solver A-SURF is used to perform transient detonation simulations of stoichiometric 50% H2-50% CO / air mixtures. Simulations for detonation wave propagation through the stoichiometric 50% H2-50% CO / air mixture with water vapor were performed with different mole fractions of water vapor and mixture gradient thicknebes to elucidate detonation extinction. From the simulations, three modes of detonation propagation through the barrier were observed: 1) normal detonation propagation, 2) detonation to deflagration transition, 3) detonation-deflagrationdetonation transition (DDDT). These modes are explained by analyzing temporal evolution of normalized reactivity gradient, E, in reaction front region.",
