The Response of Normal Shocks in Diffusers [PDF]
, 1983 The frequency response of a normal shock in a diverging channel is calculated for application to problems of pressure oscillations in ramjet engines. Two limits of a linearized analysis arc discussed: one represents isentropic flow on both sides of a ...

Shock-Wave Cosmology Inside a Black Hole [PDF]
, 2002 We construct a class of global exact solutions of the Einstein equations that extend the Oppeheimer-Snyder (OS) model to the case of non-zero pressure, {\em inside the Black Hole}, by incorporating a shock wave at the leading edge of the expansion of the

Internal stress wave measurements in solids subjected to lithotripter pulses [PDF]
, 1993 Semiconductor strain gauges were used to measure the internal strain along the axes of spherical and disk plaster specimens when subjected to lithotripter shock pulses. The pulses were produced by one of two lithotripters.

Predicted reentrant melting of dense hydrogen at ultra-high pressures
Scientific Reports, 2016 The phase diagram of hydrogen is one of the most important challenges in high-pressure physics and astrophysics. Especially, the melting of dense hydrogen is complicated by dimer dissociation, metallization and nuclear quantum effect of protons, which ...
