The progress already made in studies of the stability of shock waves and some tasks for the future are reviewed. The following aspects of the problem are discussed: 1) stability of shock waves as hydrodynamic discontinuities irrespective of the events which occur in the relaxation zone of a wave (this aspect includes also the problem of stability of a ...

An approximate theory of shock dynamics is used to study the behaviour of converging cylindrical shocks. For cylindrical shocks with regular polygonal-shaped cross sections, exact solutions are found, showing that an original polygonal shape repeats at successive intervals with successive contractions in scale.

Extracorporeal shock wave lithotripsy has significantly altered the management of symptomatic renal and ureteral calculi. Yet in an effort to limit the potentially harmful effects of shock waves, while still maintaining or maximizing stone fragmentation, one must understand basic shock wave physics. This report presents a brief overview of the physical

Interaction of a planar shock wave with a dense particle curtain: Modeling and experiments
, 2012The interaction of a planar shock wave with a dense particle curtain is investigated through modeling and experiments. The physics in the interaction between a shock wave with a dense gas-particle mixture is markedly differently from that with a dilute ...

Shock Waves, 2005
It is well known that the pressure jump across a given shock wave increases when it propagates in a conduit whose cross-section is continually reduced [1], or in a case of spherically imploding shock wave [2]. In both cases the flow cross-section is reduced toward zero.

Laser-driven shock waves (0−5 GPa) can be generated at high repetition rates (100/s) using a moderate-energy tabletop picosecond laser system and a multilayered microfabricated shock target array. High spatial resolution is needed to obtain high temporal resolution of the effects of a steeply rising shock front on molecular materials.

Reflection and Diffraction of Shock Waves and Shock-Wave Configurations
2012There are two phenomena, which can result from interaction of a shock wave (SW) with a solid surface. A SWreflects off a surface if the angle of incidence is less than 90°. If the angle of incidence is more than 90°, the shock wave diffracts over a surface.

Fifty Years of Shock-Wave/Boundary-Layer Interaction Research: What Next?
, 2001Because of their ubiquitous presence in high-speed flight and their impact on vehicle and component performance, shock-wave/boundary-layer interactions have been studied for about 50 years.
