On Entropic Framework Based on Standard and Fractional Phonon Boltzmann Transport Equations

Entropy, 2019
Generalized expressions of the entropy and related concepts in non-Fourier heat conduction have attracted increasing attention in recent years. Based on standard and fractional phonon Boltzmann transport equations (BTEs), we study entropic functionals ...

Continued-Fraction Expansion of Transport Coefficients with Fractional Calculus

Mathematics, 2016
The main objective of this paper is to generalize the Extended Irreversible Thermodynamics in order to include the anomalous transport in systems in non-equilibrium conditions.

Local equilibrium and the second law of thermodynamics for irreversible systems with thermodynamic inertia [PDF]

, 2015
Validity of local equilibrium has been questioned for non-equilibrium systems which are characterized by delayed response. In particular, for systems with non-zero thermodynamic inertia, the assumption of local equilibrium leads to negative values of the

Macroscopic Entropy of Non-Equilibrium Systems and Postulates of Extended Thermodynamics: Application to Transport Phenomena and Chemical Reactions in Nanoparticles

Entropy, 2018
In this work, we consider extended irreversible thermodynamics in assuming that the entropy density is a function of both common thermodynamic variables and their higher-order time derivatives.

Relaxation dominated cosmological expansion [PDF]

, 1996
The behavior near the singularity of an isotropic, homogeneous cosmological model with a viscous fluid source is investigated. This turns out to be a relaxation dominated regime.

Generalized van der Waals equation for nonequilibrium fluids [PDF]

, 1983
The inclusion of dissipative fluxes in the set of independent thermodynamic variables leads, among other features, to a modification of the equations of state.

A derivation of a Guyer-Krumhansl type temperature equation in classical irreversible thermodynamics with internal variables

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
In a previous paper, using the standard procedures of classical irreversible thermodynamics (CIT) with internal variables, we have shown that it is possible to describe thermal relaxation phenomena, obtaining some well-kown results in extended ...

Mesoscopic Moment Equations for Heat Conduction: Characteristic Features and Slow–Fast Mode Decomposition

Entropy, 2018
In this work, we derive different systems of mesoscopic moment equations for the heat-conduction problem and analyze the basic features that they must hold.
