We examine the interaction of both cylindrical and spherical bubbles
(2D) and a complex blast wave, which consists of an
approaching shock/contact discontinuity/shock (Kang et
al., 2001a, 2001b). Such configurations may arise
following a supernova explosion, for example, SN 1987A, where a complex
blast wave is presently approaching a high density “circumstellar
ring” (CR) (Borkowski et al., 1997).
Using simulations with the piecewise parabolic method algorithm (Colella & Woodward, 1984), we emphasize the
appearance of vortex bilayers, vortex projectiles, and turbulent domains
on the downstream and upstream sides of the bubble. We believe that the
interfacial deformation of the CR is associated with a strong blast-wave
driven accelerated inhomogeneous flow instability in a high
density medium and thus will have a different character than the more
common planar shock-driven Richtmyer–Meshkov instability.
