Mach Reflection of Random Waves

Coastal Engineering 2000, 2001
This study investigates the Mach reflection of random waves by numerical simulations and with experimental observations, especially for the difference and similarity between periodic waves and random waves. As the incident angle becomes large, the normalized significant wave height in front of a reflecting wall becomes large.

Experiments on Guderley Mach reflection

Shock Waves, 2009
Experiments have been conducted in a large shock tube to examine the four-wave shock reflection pattern, now known as Guderley reflection (GR). The fourth wave, an expansion, is clearly identified, as is the supersonic patch behind the reflected wave.

Numerical simulation of Mach reflections

Acta Mechanica Sinica, 1985
In this paper, the “FLIC” difference method with triangular mesh is adopted to numerically simulate the regular and Mach reflections that occur when a shock wave pass around a wedge. The compuational result is compared with the shock tube experimental results of G. Ben-Dor and I. I. Glass. The comparison shows that the position, shape of shock wave and

Strength of Reflected Shock in Mach Reflection

Journal of the Aeronautical Sciences, 1951
which means that along these lines of constant w the displacement of the locus of jco is proportional to the change in gain. Similar results are obtained if we let Kx be constant and vary K2. I t is now possible by simple construction to obtain the stability diagram for any combination of Kx and K2 after we have computed and plotted four loci.

The KP theory and Mach reflection

Journal of Fluid Mechanics, 2016
Interactions of two line solitons in the two-dimensional shallow-water field are studied based on the Kadomtsev–Petviashvili (KP) theory. With the use of the normal form, the extended KP equation with higher-order correction is derived. This extended KP theory improves significantly the predictability of the original KP theory for soliton interactions ...

Mach Reflection in Condensed Explosives

Propellants, Explosives, Pyrotechnics, 1981
AbstractIn an experimental setup two transparent condensed explosives of different detonation velocities are coaxially arranged to give Mach reflection in the low speed explosive (overdriven detonation). Due to the transparent characteristic of the explosive, this setup, with a suitable streak camera, is shown to give the facility of continuously ...

Analytical solution of double-Mach reflection

AIAA Journal, 1980
The double-Mach reflection (DMR) of oblique shock waves in pseudo-stationary flows has been investigated. The equations of motion of the first and second triple point were formulated, as well as the relative motion between these two triple points. The equation of motion for each triple point consists of 14 nonlinear algebraic equations.

Numerical modeling of mach reflection for solitary waves

Journal of Applied Mechanics and Technical Physics, 1993
In the article under review, the authors present results of a numerical study of a solitary wave Mach reflection from a vertical wall for various amplitudes and angles of incidence. Two discrete models of an incompressible fluid are used. As a model of the original problem, the authors obtain a finite system of material particles whose motion is ...

Study on the Mach and regular reflections of shock wave

Journal of Visualization, 2019
While a moving incident shock wave moves through a sharp compression ramp with the fixed angle, θr, the incident shock wave is reflected by the ramp surface and the induced pseudo-steady flow behind it is deflected by the ramp corner. It is known that four basic shock reflection patterns can be obtained, including regular reflection, single-Mach ...

On the Problem of Weak Mach Reflection

Journal of the Physical Society of Japan, 1964
To find clue to the well-known problem of the discrepancy in the weak Mach reflection, fundamental assumptions on which the three shock theory by von Neumann is based are examined and they are shown to become inadequate as the shock waves become weaker.
