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

Stabilized fiber-optic Mach–Zehnder interferometer for carrier-frequency rejection

, 2013
We have demonstrated stabilization of a fiber-optic Mach–Zehnder interferometer, with a centimeter-scale path difference, to the transmission minimum for the carrier wave of a frequency-modulated laser beam.

Reflection and transmission properties of double submerged rectangular blocks

, 2007
An analytic method is used to study the reflection and transmission coefficients of the double submerged rectangular blocks (DSRBs) in oblique waves.. The scattering potentials are obtained by means of the eigenfunction expansion method, and expressions ...

Experimentelle Untersuchungen zur Mach-Reflexion - von Neumann Paradox

, 1994
For about 40 years the failure of the von Neumann theory to describe correctly pseudo-steady Mach reflection of weak shock waves from inclined walls is a not sufficiently solved problem. Von Neumann's Three-Shock-Theory fails to describe the instationary
