Computing Radially-Symmetric Solutions of the Ultra-Relativistic Euler Equations with Entropy-Stable Discontinuous Galerkin Methods
Ferdinand Thein, Hendrik Ranocha
The ultra--relativistic Euler equations describe gases in the relativistic case when the thermal energy dominates. These equations for an ideal gas are given in terms of the pressu…

Self-Similar Radially Symmetric Solutions of the Relativistic Euler Equations with Synge Energy
Tommaso Ruggeri, Ferdinand Thein, Qinghua Xiao
We consider self-similar, radially symmetric solutions of the relativistic Euler equations with constitutive relations from relativistic kinetic theory, based on Synge energies for…

Radially symmetric solutions of the ultra-relativistic Euler equations in several space dimensions
Matthias Kunik, Adrian Kolb, Siegfried Müller +1
The ultra-relativistic Euler equations for an ideal gas are described in terms of the pressure, the spatial part of the dimensionless four-velocity and the particle density. Radial…
