Scientific Reports, 2023 Over the past century, understanding the nature of shock compression of condensed matter has been a major topic. About 20 years ago, a femtosecond laser emerged as a new shock-driver. Unlike conventional shock waves, a femtosecond laser-driven shock wave

Whistler mode waves upstream of Saturn [PDF]
, 2016 Whistler-mode waves are generated within and can propagate upstream of collisionless shocks. They are known to play a role in electron thermodynamics/acceleration and, under certain conditions, are markedly observed as wave trains preceding the shock ...

Thermal instability in the collisionally cooled gas
, 2011 We have presented the non-equilibrium (time-dependent) cooling rate and ionization state calculations for a gas behind shock waves with $v \sim 50-150$ km s$^{-1}$ ($T_s \sim 0.5 - 6\times 10^5$ K). Such shock waves do not lead to the radiative precursor

Observation of the shock wave propagation induced by a high-power laser irradiation into an epoxy material [PDF]
, 2013 The propagation of laser-induced shock waves in a transparent epoxy sample is investigated by optical shadowgraphy. The shock waves are generated by a focused laser (3 ns pulse duration—1.2 to 3.4TWcm−2) producing pressure from 44 to 98.9 GPa.

Sharp viscous shock waves for relaxation model with degeneracy
Advances in Nonlinear AnalysisThis article is concerned with a relaxation model with degeneracy. Different from the existing studies on the regular viscous shock waves, we recognize that when the sub-characteristic condition is degenerate, the dynamical system possesses sharp viscous

Solitary versus Shock Wave Acceleration in Laser-Plasma Interactions
, 2011 The excitation of nonlinear electrostatic waves, such as shock and solitons, by ultraintense laser interaction with overdense plasmas and related ion acceleration are investigated by numerical simulations.

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Numerical evaluation of shock wave effects on turbulent mixing layers in a scramjet combustor
Case Studies in Thermal Engineering, 2021 ABSTRCT: The effects of shock waves on turbulent mixing layers in a supersonic combustor are investigated. An asymmetric scramjet combustor with strut designed and tested by German Aerospace Center is taken as the physical model.

Cherenkov-like shock waves associated with surpassing the light velocity barrier [PDF]
, 1999 The effects arising from accelerated and decelerated motion of a point charge inside a medium are studied. The motion is manifestly relativistic and may be produced by a constant uniform electric field.
