Transition from Slow Burning to Detonation. Flame Fronts and Compression Waves During Growth of Detonation
Abstract
A group of experiments Is described which elucidates details of propagation of flame fronts, pressure fronts and shock fronts during build-up of steady state detonation. The experimental evidence gives further support to the previously proposed theory that the transition proceeds essentially through two steps, shock formation and shock initiation of detonation. The measurements demonstrate the existence of a flame front which propagates at a fraction of the detonation velocity (1-2 mm/microsecs) for as much as 60 microsecs and then goes over into steady state detonation within a few microseconds. A proposed explanation of the transition phenomenon is given and discussed.
