Planar Detonation Wave Initiation in Large-Aspect-Ratio Channels

Planar detonation waves are often created in narrow rectangular channels to more easily visualize the cellular structure of gaseous detonation waves.1–6 Typically, these detonation waves are initiated from a single high energy source requiring several kilojoules of input energy, such as a strong spark or exploding wire that creates a spherically or cylindrically expanding wave. This wave is then diffracted until its radius of curvature i
