Evolution of unstable explosion shock wave: Generation and transformation
We present our discovery of unstable shock trains induced by transmission of unsteady detonation wave with electromagnetic and optical measurements. It reveals that transmission of explosion shock wave is essentially a transfer of state between matter with high energy densities and disturbed medium, and the wave structure depends on the uniformity of energy densities. The generation of transmitted shock wave differs generation of shock wave in the piston problem. This study could form theoretical and experimental basis of unsteady shock wave structure and foster further understanding the mechanism for generation of shock wave.
