  • Laboratory studies of hydrodynamic effects driven by a flowing, expanding plasma of high-energy density and high Mach number are reported. The flowing plasma is the ejecta from matter accelerated and heated by an ablative shock. X-ray backlighting diagnoses the structure produced when this plasma impacts low-density foam. We observe the forward shock driven into the foam and the stagnated ejecta which drives a reverse shock into the flow. {copyright} {ital 1998} {ital The American Physical Society}
  • The Richtmyer-Meshkov (RM) instability is an interfacial interface between two fluids of different densities driven by shock waves and plays an important role in the studies of inertial confinement fusion and of supernovas. So far, most of the studies are for RM unstable interfaces driven by weak or intermediate shocks in planar geometry. For experiments conducted at the Nova laser, the unstable material interface is accelerated by very strong shocks. In this Letter, we present scaling laws for the RM unstable interface driven by strong imploding and exploding shocks. {copyright} {ital 1997} {ital The American Physical Society}
  • The Richtmyer{endash}Meshkov instability is investigated with strong radiatively driven shocks (Mach{approx_gt}20, 5{times}compression) using the Nova laser. The target consists of a solid density ablator and lower-density plastics (Atwood number {ital A}{lt}0) in planar geometry to facilitate in-flight radiographic diagnosis. Perturbations {eta}={eta}{sub 0}cos{ital kx} are imposed at the interface to seed the instability. The experiments agree with full hydrodynamic simulations over a wide variety of conditions. For small initial amplitudes {parallel}{ital A}{parallel}{ital k}{eta}{sub 0}{lt}1, the growth rate agrees with a linear impulsive model using the average of the pre- and post-shock initial amplitudes. For {parallel}{ital A}{parallel}{ital k}{eta}{sub 0}{approx_gt}1, the growth ratemore » is limited to the difference between the transmitted shock speed and the interface speed. {copyright} {ital 1996 American Institute of Physics.}« less
  • The Richtmyer{endash}Meshkov instability is investigated in the turbulent regime with strong radiatively driven shocks (Mach {gt}10) on the Nova laser [Phys. Rev. Lett. {bold 70}, 1806 (1993)]. The targets are planar with near solid density and Atwood number {approximately}{minus}0.9. The interfacial perturbations are three dimensional (3-D), random, and nonlinear with a broad scale distribution such that they develop into a turbulent mixing zone (TMZ). The TMZ is diagnosed radiographically using x-ray dopants localized to the center of the target to avoid edge effects. Two different diagnostic configurations yield comparable results. The total width of the TMZ is found to increasemore » in time as H{approximately}t{sup {Theta}}, with {Theta}{approximately}0.5{plus_minus}0.1. When compared to shock tube data, this result supports the suggestion [Phys. Fluids {bold 8}, 614 (1996)] that {Theta} decreases with Mach number. The data are used to test turbulence models and to determine the effective drag coefficient C{sub d}{approximately}2.6{plus_minus}1.2 for potential flow mix models in the high compression regime. {copyright} {ital 1997 American Institute of Physics.}« less
