The book aims to present the recent developments in Rational Extended Thermodynamics
(RET) of gases in both classical and relativistic cases. The RET theory is a …

We present a more refined version of rational extended thermodynamics of rarefied
polyatomic gases in which molecular rotational and vibrational relaxation processes are …

The aim of this paper is to compare different kinetic approaches to a polyatomic rarefied gas:
the kinetic approach via a continuous energy parameter I and the mixture-like one, based on …

Based on a continuous internal energy state variable, we propose an explicit, fully nonlinear
Boltzmann collision operator for the evolution of the distribution function describing a …

After summarizing the present status of Rational Extended Thermodynamics (RET) of gases,
which is an endeavor to generalize the Navier–Stokes and Fourier (NSF) theory of viscous …

Recently a new relativistic model of polyatomic gases has been proposed, by Arima-Carrisi-
Pennisi-Ruggeri (2022), in the context of Rational Extended Thermodynamics. It is based on …

We propose a possible generalization of the BGK collisional term in the relativistic kinetic
theory and we compare our model with previous ones. The present model has the …

In hyperbolic dissipative systems, the solution of the shock structure is not always
continuous and a discontinuous part (sub-shock) appears when the velocity of the shock …

This paper is concerned with the analysis of polyatomic gases within the framework of
kinetic theory. Internal degrees of freedom are modelled using a single continuous variable …

Recently Pennisi and Ruggeri [Ann. Phys. 377, 414 (2017)] proposed a casual hyperbolic
model for a dissipative relativistic gas with internal structure. In this paper, we consider the …
