Study on Mach Stem Shape of the Asymmetric Overall Mach Reflection

2019
In this paper, the Mach stem shape of the asymmetric overall Mach reflection is studied analytically. Based on the experimental results, we can conclude that the angle difference between two wedges would result in the flow deflection. Then, we assume the Mach stem is ellipse shaped.

Dependence of Steady Mach Reflections on the Reflecting-Wedge Trailing-Edge Angle

AIAA Journal, 1997
Two simultaneous numerical investigations, using different codes, were conducted. The numerical method, in the first study, was the LCPFCT algorithm, which is a one-dimensional flux corrected transport algorithm, for solving generalized continuity equations, with fourth-order phase accuracy and minimum residual diffusion.

On the Mach reflection of a solitary wave: revisited

Journal of Fluid Mechanics, 2011
Reflection of an obliquely incident solitary wave at a vertical wall is studied experimentally in the laboratory wave tank. Precision measurements of water-surface variations are achieved with the aid of laser-induced fluorescent (LIF) technique and detailed features of the Mach reflection are captured.

Mach reflection parameters for plexiglas cylinders

Journal of Applied Mechanics and Technical Physics, 1969
The “collapsing air gap” method has been used to investigate the development and limiting parameters of the Mach reflection of a conical convergent shock in plexiglas cylinders arranged along the axis of a detonating explosive charge. The diameters of the cylindrical specimens varied from 15 to 100 mm.

Mach reflection in a warm dense plasma

Physics of Plasmas, 2010
The phenomenon of irregular shock-wave reflection is of importance in high-temperature gas dynamics, astrophysics, inertial-confinement fusion, and related fields of high-energy-density science. However, most experimental studies of irregular reflection have used supersonic wind tunnels or shock tubes, and few or no data are available for Mach ...

Mach reflection of cellular detonations

2014
Une étude de la réflexion de Mach sur des détonations cellulaires à été fait dans ce mémoire. Les détonations sont propagées dans des mixtures de C2H2 + 2.5O2 , C2H2 + 2.5O2 + 70% Ar et C3H8 + 5O2 pour des pressions initiales de 3 kPa < Po < 20 kPa. Des coins aux angles de 10°, 20°, 30°, 35° and 40° ont été utilisé.

Numerical calculations of complex Mach reflection

17th Fluid Dynamics, Plasma Dynamics, and Lasers Conference, 1984
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 time-asymptotic solutions of the two-dimensional, unsteady Euler equations.

Single-Mach and double-Mach reflection — its representation in Ernst Mach’s historical soot method

1992
In 1875 Ernst Mach discovered the effect of irregular interaction of shock waves, the so-called single Mach reflection (SMR), which for symmetric geometry is characterized by two triple points. He recorded their two trajectories on a soot-covered glass plate.

Mach waves and reflected rarefactions in aluminum

Journal of Applied Physics, 1975
A rarefaction wave in aluminum shocked to 27.7 GPa (277 kbar) is examined with radiographic techniques, and the bulk sound speed is determined. A Mach reflection in aluminum is also examined radiographically and the results are compared with the simple three-shock theory of Mach waves.

Numerical simulation of regular and Mach reflections

The Physics of Fluids, 1975
The results of an M∞=2 shock wave propagating in air down a shock tube and impinging on a wedge were calculated using both a two-dimensional Eulerian code and a two-dimensional Lagrangian code. The air was considered to be an ideal gas with γ=1.4. Both 2:1 and 1:2 wedges were used; these angles are known to generate regular and Mach reflected shock ...
