Speeds of Propagation in Classical and Relativistic Extended Thermodynamics [PDF]

open access: greenLiving Reviews in Relativity, 1999
The Navier-Stokes-Fourier theory of viscous, heat-conducting fluids provides parabolic equations and thus predicts infinite pulse speeds. Naturally this feature has disqualified the theory for relativistic thermodynamics which must insist on finite ...

Some Implications of a Scale Invariant Model of Statistical Mechanics to Classical and Relativistic Thermodynamics

open access: goldInternational Journal of Thermodynamics, 2014
Some implications of a scale invariant model of statistical mechanics to the mechanical theory of heat of Helmholtz and Clausius are described. Modified invariant definitions of heat and entropy are presented closing the gap between radiation and gas theory. Modified relativistic transformations of pressure, Boltzmann constant, entropy, and density are

Thermodynamics of Intrinsic Reaction Coordinate (IRC) Chemical Reaction Pathways [PDF]

open access: yesEntropy
We address the scientific “time” concept in the context of more general relaxation processes toward the Wärmetod of thermodynamic equilibrium. More specifically, we sketch a construction of a conceptual ladder of chemical reaction steps that can ...

Limits of Relativist Process Engineering: Current Feasibility in the International Space Station (ISS) [PDF]

open access: yesMATEC Web of Conferences, 2023
Many authors have published in the field of relativistic fluid mechanics (Von LAUE, 1911) (HALBWACHS, 1960) (PICHON, 1965) (LICHNEROWICZ, 1966) (BRUHAT, 1966) (MARLE, 1969) (ARZELIES, 1971) (MAHJOUB, 1971) (REZZOLLA et al., 2013) (DISVONZI, 2014 ...

Unified Extended Irreversible Thermodynamics and the Stability of Relativistic Theories for Dissipation

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In a relativistic context, the main purpose of Extended Irreversible Thermodynamics (EIT) is to generalize the principles of non-equilibrium thermodynamics to the domain of fluid dynamics.

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid

open access: yesPhysics Letters B, 2022
We establish the nonlocal generalization of the Israel-Stewart model for the relativistic causal thermodynamics of the cosmic fluid, which evolves in the homogeneous isotropic Universe.

Molecular Extended Thermodynamics of Rarefied Polyatomic Gases with a New Hierarchy of Moments

open access: yesFluids, 2021
The aim of this paper is to construct the molecular extended thermodynamics for classical rarefied polyatomic gases with a new hierarchy, which is absent in the previous procedures of moment equations.

Modified Friedmann equations from Kaniadakis entropy and cosmological implications on baryogenesis and $${}^7 Li$$ 7 L i -abundance

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Modified Friedmann equations have been recently derived by implementing the gravity-thermodynamics conjecture in Kaniadakis statistics, which is a relativistic self-consistent generalization of the classical Boltzmann–Gibbs theory.
