The monatomic limit of polyatomic gases as concentration of the internal-energy measure
Tommaso Ruggeri
In Rational Extended Thermodynamics, the monatomic limit of polyatomic gases is often singular. For the internal-state density , with , we prove that the norma…

Rational Extended Thermodynamics for Non-Newtonian Fluids with Finite Relaxation Time
Tommaso Ruggeri
We introduce a one-dimensional, hyperbolic model for non-Newtonian fluids with finite relaxation time, derived within the framework of Rational Extended Thermodynamics (RET). Unlik…
