“…A study by Li et al 7 also noted that a transmitted overdriven detonation wave occurs when there is a strong incident overdriven detonation wave. Krivosheev and Penyaz'kov 8 found that the value of the critical pressure for successful wave transmission is reduced by a factor of 3-5 when there is an overdriven detonation wave.…”

This study determines the effect of the initial pressure on the propagation of a Chapman-Jouguet detonation wave from a stoichiometric C 3 H 8 /O 2 mixture (donor) to a stoichiometric C 3 H 8 /air mixture (acceptor). Depending on the initial pressure ratio in the donor and the acceptor, the result can be a smooth transmission, a re-initiated detonation wave, or a transmitted shock wave. When the donor is divided into a driver donor and a driven donor, the degree of overdrive in a driven donor varies with the donor pressure ratio. There must be a greater degree of overdrive in the driven donor for re-initiation of a detonation wave in the acceptor, particularly if the initial pressure in the driven donor is lower than the Chapman-Jouguet pressure in the acceptor. The bi-dimensional effect is also another major factor.
