Abstract

The numerical study of the implosion of a cylinder driven by an azimuthally varying pressure has shown that two regimes can exist for the evolution. In the first regime the cylinder implodes almost symmetrically; while in the second, energetic jets appear behind the shock wave, thus destroying the implosion uniformity. Scaling laws for the threshold of the transition between these two regimes are given as a function of the relevant dimensionless parameters for both ideal gases and real matter.
