Abstract
Using a detailed kinetic mechanism of chemical interaction, the effect of adding ozone (or hydrogen peroxide) and helium as an inert diluent to a stoichiometric hydrogen-air mixture on the detonation wave parameters was numerically studied. It was found that the mole fractions of the additives can be selected such that the detonation wave cell size in the resulting mixture is close to the average cell size in the pure mixture, while the temperature of the detonation products is significantly reduced. It was shown that the introduction of hydrogen peroxide and helium reduces the stability of the detonation wave to disturbances caused by multiple obstacles (barriers) located in the channel, thereby contributing to the wave suppression. Conversely, detonation in a mixture with ozone and helium additives at selected concentrations is found to be more resistant to these disturbances than in the pure mixture.
