Effect of Rayleigh-Taylor instability on the structure of explosive cylindrical flow
Abstract
A pulsed X-ray technique was used to study the effect of Rayleigh-Taylor instability on the structure of explosive cylindrical flow. The results generally confirm the validity of the mechanism found theoretically by Anisimov and Zel'dovich (1977, 1982) for the onset of this instability in explosive flows; the validated mechanism is related to the fact that the bow zone of a cylindrical explosive flow is bounded by two pressure and density shocks, with density discontinuity at the contact surface. It is also shown that jets of cold detonation products penetrate across a layer of shock-heated gas and that these products move out ahead of the shock front.
