Shock Waves:

British Music after Britten, 2020
Shock waves arise in supersonic and energetic flows, but are especially prevalent in high-speed aerospace applications. They are characterized by a nearly discontinuous jump in kinetic and thermodynamic properties.

Wave-function shock waves

Physical Review A, 1992
When a Rydberg state is suddenly excited to an autoionizing Rydberg state by a short-pulse core-electron excitation, a shock wave is created in the Rydberg electron's wave function. This shock wave originates at small r, at the excited core, and propagates outward.

Interstellar Shock Waves

Science, 1991
An understanding of interstellar shock waves is crucial in determining the structure of the interstellar medium. By causing the gas to radiate, interstellar shocks provide astronomers with valuable diagnostics on both the physical conditions in the interstellar medium and the energy source that produced the shock.

Effect of shock waves on thermophysical properties of ADP and KDP crystals

Optics and Laser Technology, 2019
Ammonium Dihydrogen Phosphate (ADP) and Potassium Dihydrogen Phosphate (KDP) crystals are grown by slow evaporation method at ambient temperature. The said crystals are utilized as a test specimen and subjected to one-dimensional ‘loading of shock waves’

Influence of shock waves on supersonic transpiration cooling

International Journal of Heat and Mass Transfer, 2019
This paper experimentally and numerically investigates the effect of shock waves on transpiration cooling of a porous plate. The experiments were conducted in a wind tunnel of Mach number 2.8, wherein oblique shock waves were impinged onto the porous ...

Attosecond Shock Waves

Physical Review Letters, 2013
Shock-wave formation is a generic scenario of wave dynamics known in nonlinear acoustics, fluid dynamics, astrophysics, seismology, and detonation physics. Here, we show that, in nonlinear optics, remarkably short, attosecond shock transients can be generated through a strongly coupled spatial and temporal dynamics of ultrashort light pulses ...

DELTA SHOCK WAVES AS A LIMIT OF SHOCK WAVES

Journal of Hyperbolic Differential Equations, 2007
We discus the existence of delta shock waves obtained as a limit of two shock waves. For that purpose we perturb a prototype of weakly hyperbolic 2 × 2 system (sometimes called the "generalized pressureless gas dynamics model") by an additional term (called the "generalized vanishing pressure"). The obtained perturbed system is strictly hyperbolic and

Analysis of the ignition induced by shock wave focusing equipped with conical and hemispherical reflectors

Combustion and Flame, 2022
The interaction of a plane shock wave in air with concave profiles has been used in the past to understand the nature of shock wave focusing. The current study examines the complex two-dimensional flow field resulting from the interaction of a plane ...
