MACH REFLECTION PHENOMENON IN THE INTERACTION OF SPHERICAL SHOCK-WAVES IN AIR

, 1991
Mutual interaction of two spherically symmetric shock waves propagating in air is studied using different optical methods, namely holographic interferometry and shadowgraphy. The experimental results, showing the onset of Mach reflection in the region of

Study on the Mach Reflection of Detonation Waves

DEStech Transactions on Environment, Energy and Earth Sciences, 2018
In order to know the basic characteristics of Mach relection effect, computing and experimental research on Mach reflection is conducted which is likely to formed in the course of the explosion which will break buildings and other objects and cause the loss of injuries and property damage.Firstly, the paper conducts comprehensive compare and analysis ...

An Experimental Study of Particle‐Laden Jet Noise as an Analogue to Tephra‐Laden Volcanic Eruptions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Explosive volcanic eruptions produce vast amounts of acoustic energy, generally in the infrasound range. For sustained eruptions, infrasound is often dominated by jet noise, a form of noise similar to the sound from human‐made jet engines. Jet noise largely results from the combination of two sound‐producing components: fine‐scale turbulence ...

Detection and Analysis of an Upward Jet‐Like Electrical Discharge Intercepting a High‐Altitude Research Aircraft

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.

Mach reflection of spherical detonation waves [PDF]

, 1993
When two detonation waves collide, the shape of the wave front at their intersection can be used to categorize the flow as regular or irregular reflection. In the case of regular reflection, the intersection of the waves forms a cusp.

A model to predict the Mach reflection of the separation shock in rocket nozzles

, 2009
In case of high overexpansion, the exhaust jet of the supersonic nozzle of rocket engines separates from nozzle wall because of the large adverse pressure gradient. At the same time, to match the pressure of the separated flow region, an oblique shock is

Complex Mach reflection in shock diffraction problems [PDF]

, 1985
Numerical simulations of the interaction of a planar blast wave with a compression ramp are presented. The split coefficient matrix (SCM) method in conjunction with boundary shock and floating discontinuity-fitting procedures was employed to obtain the ...
