Port contact systems for irreversible thermodynamical systems [PDF]

open access: yes, 2005
In this paper we propose a definition of control contact systems, generalizing input-output Hainiltonian systems, to cope with models arising from irreversible Thermodynamics.

Metrics and Energy Landscapes in Irreversible Thermodynamics

open access: yesEntropy, 2015
We describe how several metrics are possible in thermodynamic state space but that only one, Weinhold’s, has achieved widespread use. Lengths calculated based on this metric have been used to bound dissipation in finite-time (irreversible) processes be ...

Extended irreversible thermodynamics and non-equilibrium temperature

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
We briefly review the concept of non-equilibrium temperature from the perspectives of extended irreversible thermodynamics, fluctuation theory, and statistical mechanics. The relations between different proposals are explicitly examined in two especially

Time & clocks: A thermodynamic approach

open access: yesResults in Physics, 2020
Recently, the definition of time has been introduced by introducing the irreversible thermodynamics into the analysis of the atomic irreversibility. In this way, time is defined by means of the entropy generation and the entropy rate.

The Multielectrodes Oscillation System Studied by Irreversible Thermodynamics

open access: yesIndonesian Journal of Chemistry, 2010
Oscillation process that occurs in a system may be formed from non linear dynamic phenomena that far from equilibrium. Mechanism of oscillation in a chemical reaction system such as Belousov-Zhabotinski (B-Z) reaction is quite complex.

Power-efficiency-dissipation relations in linear thermodynamics [PDF]

open access: yes, 2016
We derive general relations between maximum power, maximum efficiency, and minimum dissipation regimes from linear irreversible thermodynamics. The relations simplify further in the presence of a particular symmetry of the Onsager matrix, which can be ...

Thermodynamically consistent gradient elasticity with an internal variable [PDF]

open access: yesTheoretical and Applied Mechanics, 2020
The role of thermodynamics in continuum mechanics and the derivation of proper constitutive relations is a topic discussed in Rational Mechanics. The classical literature did not use the accumulated knowledge of thermostatics and was very critical of the

Weakly nonlocal irreversible thermodynamics

open access: yes, 2003
Weakly nonlocal thermodynamic theories are critically revisited. A relocalized, irreversible thermodynamic theory of nonlocal phenomena is given, based on a modified form of the entropy current and new kind of internal variables, the so called current ...

Irreversible Thermodynamics of Seawater Evaporation

open access: yesJournal of Marine Science and Engineering
Under typical marine conditions of about 80% relative humidity, evaporation of water from the ocean is an irreversible process accompanied by entropy production.

Collective dynamics from stochastic thermodynamics

open access: yesNew Journal of Physics, 2015
From a viewpoint of stochastic thermodynamics, we derive equations that describe the collective dynamics near the order-disorder transition in the globally coupled XY model and near the synchronization–desynchronization transition in the Kuramoto model ...
