Abstract

We present X-ray radiograms from a high Mach number "complex" blast wave interacting with a high-density (100 times the ambient) sphere using a laser produced plasma. We show visualizations of data from comparable parameter two-dimensional axisymmetric hydrodynamic simulations, including density, dilatation (div u), and vorticity (curl u). The simulation results are consistent with the X-ray radiograms, thus providing heuristic guidance for future studies
