Non equilibrium thermodynamics with internal variables in Kluitenberg's theory

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
We show a method to verify experimentally some inequalities which occur for phenomenological coefficients in the thermodynamical model for dielectric relaxation and viscoanelastic media developed in the ambit of non-equilibrium thermodynamic Kluitenberg ...

A Novel Derivation of the Time Evolution of the Entropy for Macroscopic Systems in Thermal Non-Equilibrium

open access: yesEntropy, 2017
The paper discusses how the two thermodynamic properties, energy (U) and exergy (E), can be used to solve the problem of quantifying the entropy of non-equilibrium systems.

Exergy Dynamics of Systems in Thermal or Concentration Non-Equilibrium

open access: yesEntropy, 2017
The paper addresses the problem of the existence and quantification of the exergy of non-equilibrium systems. Assuming that both energy and exergy are a priori concepts, the Gibbs “available energy” A is calculated for arbitrary temperature or ...

Time and thermodynamics extended discussion on “Time & clocks: A thermodynamic approach”

open access: yesResults in Physics, 2020
In the paper, “Time & clocks: A thermodynamic approach” Lucia and Grisolia describe the connections between the physical nature of time and macroscopic irreversibility in thermodynamics.

Informational statistical thermodynamics and thermal laser stereolithography [PDF]

open access: yes, 2015
We consider the nonequilibrium thermodynamic aspects of the techno-industrial process of thermal laser stereolithography. The conditions necessary for a satisfactory process of rapid prototyping to follow are characterized and discussed. We show that the

Thermodynamics of exponential Kolmogorov–Nagumo averages

open access: yesNew Journal of Physics, 2023
This paper investigates generalized thermodynamic relationships in physical systems where relevant macroscopic variables are determined by the exponential Kolmogorov–Nagumo average.

A zero emission scheme for producing energy from natural gas hydrates and conventional natural gas

open access: yesPetroleum, 2021
The global amount of energy contained in natural gas hydrates is huge, maybe as much as twice all known conventional fossil fuel resources. Unlike the worldwide distribution of conventional fossil fuels, hydrocarbons trapped in water as hydrate is also ...

Exploring quantum thermodynamics with NMR

open access: yesJournal of Magnetic Resonance Open, 2023
Quantum thermodynamics seeks to extend non-equilibrium stochastic thermodynamics to small quantum systems where non-classical features are essential to its description.

Hot and Heavy Matters in the Foundations of Statistical Mechanics [PDF]

open access: yes, 2010
Are the generalizations of classical equilibrium thermodynamics true of self-gravitating systems? This question has not been addressed from a foundational perspective, but here I tackle it through a study of the "paradoxes" commonly said to afflict such ...

MICROSCOPIC APPROACH TO IRREVERSIBLE THERMODYNAMICS .4. AN EXAMPLE OF GENERALIZED DIFFUSION AND WAVE-EQUATIONS [PDF]

open access: yes, 2015
The theory presented in part III of this series of articles [1], based on Informational Statistical Thermodynamics, provides a far-reaching generalization of the constitutive equations of Linear Irreversible Thermodynamics, recovering as a particular ...
