Detonation Initiation by Shock Wave Interaction with the Prechamber Jet Ignition Zone

摘要

Detonation initiation in a stoichiometric propane-air mixture by controlled shock wave(SW)interaction with the cloud of hot combustible gas forming upon the discharge of a combustion product jet from the prechamber has been experimentally observed for the first time.It has been shown that detonation initiation requires the careful synchronization of the SW arrival at the cloud with the moment of spontaneous ignition in it.
