On the Deflagration-to-Detonation Transition in Narrow Tube with Varying Prechamber-Initiator

Abstract

Prechamber method of detonation initiation is most relevant for the dissemination of research of combustion in a narrow channel, i.e., in such channel, the diameter of which is less than or comparable with the detonation cell width gas mixture. The transition slow burning to detonation in these channels is virtually impossible to carry out due to the heat sink wall and the significant effect of the boundary layer.
