Abstract

In an experimental setup two transparent condensed explosives of different detonation velocities are coaxially arranged to give Mach reflection in the low speed explosive (overdriven detonation). Due to the transparent characteristic of the explosive, this setup, with a suitable streak camera, is shown to give the facility of continuously recording the phenomenon of Mach reflection before as well as after its formation. The important characteristics of Mach reflection, viz., triple point growth angle, Mach‐disc configuration and its dimension, and propagation velocity can now be accurately and continuously measured; also the information on the transients before the formation of Mach reflection is made available. The possibility of generating these data continuously with the improved accuracy will help in better understanding of Mach‐reflection phenomenon.
