Abstract
Mechanisms for the initiation of autoignition in hydrogen-air mixtures in a supersonic flow behind a shock at temperatures ≤700 K when the H2 and N2 molecule vibration is selectively excited are considered. By exciting molecular vibration in the gases, one can initiate detonation combustion behind the shock front even at weak shocks at gas temperatures ≤500 K. It is established that even a small (<0.15%) amount of vibrationally excited ozone present in the reacting mixture may considerably shrink the induction zone.
