Optimal regular reflection of shock and blast waves
MATEC Web of Conferences, 2018 The regular reflection of an oblique steady shock in supersonic gas flow is considered. The static pressure extremum conditions after the point of reflection of the shock with fixed strength depending on oncoming flow Mach number are determined ...

Shock reflection and surface effects in the shock tube [PDF]
, 1966 A thin-film resistance thermometer, mounted on the end-wall of a shock tube, is used to record surface temperatures and heat transfer rates following reflection of the primary shock wave. This information is combined with the results of theoretical investigations to produce simultaneous information about surface accommodation effects and gas thermal ...

Ion Reflection by a Rippled Perpendicular Shock
Physical Review LettersWe use multi-spacecraft Magnetospheric Multiscale (MMS) observations to investigate electric fields and ion reflection at a non-stationary collisionless perpendicular plasma shock. We identify sub-proton scale (5-10 electron inertial lengths) large-amplitude normal electric fields, balanced by the Hall term ($\mathbf{J} \times \mathbf{B}/ne$), as a ...

Colliding micro-shock waves [PDF]
Scientific ReportsShock waves, disturbances that propagate with supersonic velocity in a fluid, are prevalent in nature and across nearly all natural sciences. They find diverse applications in fields such as medicine, aerospace engineering and physical chemistry, where ...

Comparison of weak shock reflection factors for wedges, cylinders and blast waves
, 2022 The paper presents a comparison of reflection factors (R Xi Deltapr/DeltapI) for weak-shock reflections from various surfaces. Three cases are considered: (i) square wave planar shock reflections from wedges, (ii) square wave planar shock reflections ...

The influence of wall and shock curvature on shock reflection processes
, 2022 S.543-549 : Abb.,Tab.,Lit.The paper deals with the transition conditions from regular to irregular two-dimensional shock wave reflection at a convex curved obstacle in air and with the subsequent modes of irregular reflection determined by these ...

On the origin of field-aligned beams at the quasi-perpendicular bow shock: multi-spacecraft observations by Cluster [PDF]
Annales Geophysicae, 2004 Two distinct populations of reflected and accelerated ions are known to originate from quasi-perpendicular shocks, gyrating ions and reflected ion beams.

Interaction between Shock Waves Travelling in the Same Direction
Fluids, 2021 In this paper, we study the intersection (interaction) between several steady shocks traveling in the same direction. The interaction between overtaking shocks may be regular or irregular. In the case of regular reflection, the intersection of overtaking

A code-based study of the pseudo-steady shock reflection process
, 2022 Numerical calculations of the shock wave reflection at plane inclined walls (wedges) were performed applying the Code SHARC. The parametrical study made for incident shock Mach numbers of 1.37 and 2.55 covered a wedge angle range from 40degree to ...

Propagation of Shock Waves of Varying Curvature
Journal of Applied Fluid Mechanics, 2021 When a shock wave having variable concave curvature propagates, it can develop a kink followed by the development of a reflected shock. A typical example is a plane incident shock encountering a surface with concave curvature, the part of the shock ...
