Nonisothermal Shock Structure and Universal Flow-Index Thresholds in a Hyperbolic Power-Law Fluid
Tommaso Ruggeri
We investigate whether the two flow-index thresholds previously found for isothermal shock profiles persist when the full nonisothermal dynamics is taken into account in a hyperbol…

Six-Field Rational Extended Thermodynamics of Polyatomic Gases in Curved Spacetime
Luca Gallerani, Andrea Giusti, Andrea Mentrelli +1
The paper develops a generally covariant six-field Rational Extended Thermodynamics model for relativistic polyatomic gases, couples it to Einstein’s equations, and studies its cos…
