Deflagration-to-Detonation Transition of Methane-Oxygen Mixtures in Narrow Tubes

摘要

The effect of geometrical parameters of the prechamber on the deflagration-to-detonation transition in the subcritical diameter channel had been investigated. There were observed several scenarios of combustion propagation in narrow channel with the prechamber. It was proposed a non-dimensional criterion defining these scenarios. This criterion defines an effectiveness of prechamber effect on deflagration-to-detonation transition in subcritical channels. It demarcates different scenarios of detonation formation in the narrow channel.
