Numerical simulation of multi-dimensional structure and Mach reflection of gaseous detonation waves

, 2001
When a detonation wave interacts with a wedge, the Mach reflection is occured. In this paper the DDT process of combustible gases and Mach reflection of detonation waves have been simulated numerically with a new CE/SE method.

Numerical study on the influence of jet on the stability of oblique detonation waves in confined space

Propulsion and Energy
In confined spaces, due to various interfering factors, oblique detonation waves inevitably reflect off the walls, resulting in the formation of a Mach stem.

Metasurface‐Enabled Single‐Shot Intensity‐and‐Phase‐Interrogation Surface‐Plasmon‐Resonance Microscopy

Laser &Photonics Reviews, EarlyView.
A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

Study of Mach Reflection in Inviscid Flows

In this paper, we study the Mach reflection phenomenon in inviscid flows using a higher order discontinuous Galerkin method and overset grids. We use the shock capturing procedure proposed in Siva Prasad Kochi et al. using overset grids to capture the discontinuities occurring in the supersonic flow over a wedge accurately. In this procedure, we obtain

Investigations of Mach Reflection of a Shock Wave : 4th Report, The Transition between Regular and Mach Reflections

Bulletin of JSME, 1986
The transition between regular and Mach reflections of an oblique shock wave has been investigated by many researchers for steady, pseudo-steady and unsteady flows. However the problem for unsteady flows such as the reflection of a shock wave at cylindrical concave or convex walls has not been fully understood.

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

High Pressure Hugoniot Measurements in Solids Using Mach Reflections [PDF]

, 2011
Shock compression experiments provide access to high pressures in a laboratory setting. Matter at extreme pressures is often studied by utilizing a well controlled planar impact between two flat plates to generate a one dimensional shock wave.
