Abstract:
The effect of preliminary preparation of a stoichiometric hydrogen–air mixture (decomposition of a part of molecular hydrogen and molecular oxygen into atomic gases) on the characteristics of a propagating detonation wave is numerically studied using a detailed kinetic mechanism of chemical interaction. It is revealed that this preliminary dissociation leads to a significant reduction in the transverse size of the detonation cell with a slight increase in the propagation velocity of the self-sustained wave, which allows using this preparation to prevent detonation damping in channels with both a single obstacle and multiple barriers.
Keywords:
plane channel, detonation, barrier, conservation/quenching of detonation combustion.
