Abstract

One-dimensional H₂-Air detonation is numerically studied. The simulations are carried out with various parameters, such as degree of overdrive, initial pressure, and equivalence ratio. Steady state, high-frequency mode, and low-frequency mode are observed in this order, when the degree of overdrive reduces. Although the order of the transition of oscillation mode does not depend on the initial pressure or the equivalence ratio change, the degree of overdrive of transition mode does. When the initial pressure is higher or the equivalence ratio is not stoichiometric, the degree of overdrive is higher.
