We present new equation-of-state (EoS) data acquired by shock loading to pressures
up to 245 GPa on both low-density samples (MgSiO3
glass) and high-density,
Shock-free Solutions of the Compressible Euler Equations
Conservation laws compressible Euler equations singularity formation large data exact solutions

2012/4/18
We study the structure of shock-free solutions of the compressible Euler equations with large data. We describe conditions under which the Rarefactive/Compressive character of solutions changes, and c...
A Comparison of Cosmological Codes: Properties of Thermal Gas and Shock Waves in Large Scale Structures

Abstract: We show that under rather general assumptions on the form of the entropy function, the energy balance equation for a system in thermodynamic equilibrium is equivalent to a set of nonlinear e...
Rarefaction Shock Waves in Collisionless Plasma with Electronic Beam
Collisionless plasma, Supersonic ion-acoustic rarefaction shock waves
font style='font-size:12px;'>
2011/9/9
We show that an electronic beam passing through the collisionless plasma of the ”cold” ions and the ”hot” Boltzmann electrons can give rise to the propagation of the supersonic ion-acoustic rarefactio...
