Abstract

We study dynamic interactions between a shock-induced Sn cavitation bubble with a Richtmyer-Meshkov unstable (RMU) sheet and spike in explosively driven, colliding shockwave, cylindrical geometries. The Sn surface finishes were mirror like and smooth, or included a scallop-or divot-perturbation in the Sn above the collision axis. In all cases a cavitation bubble formed in the Sn, with an RMU-sheet or-spike on the scallop-and divot-tests: the unstable sheet sliced the bubble open, but the spike punctured it. As the shockwaves released from the perturbation a cavitation-wave transverse to the shockwave formed, sourcing mass into the sheet and spike. In the case of the divot test, the transverse cavitation wave penetrated through the Al cylinder, releasing Al and HE products beyond the cylinder surface. Surprisingly, on the divot test the cavitation bubble imploded, sealing the ruptured tube after a few microseconds.
