Detonation-propelled shocks in tubular charges as a two-phase problem

The article is concerned with the experimentally known phenomenon of the precursor shock driven by the detonation of a tubular charge. It is shown that the basic aspects of the effect may be successfully captured within a one-dimensional two-phase version of the Chapman–Jouguet (CJ) theory. A modified CJ principle for determination of the detonation and precursor shock velocities is...
