Special Issue Information

Dear Colleagues,

The Joint European Thermodynamics Conference is a biannual congress with a high level of participation from the scientific community working in the field of thermodynamics. The JETC conferences were established in 1989 under the name Journées Européennes de Thermodynamique Contemporaine by ECAST, the European Center for Advanced Studies in Thermodynamics. As it was desirable to enlarge the scope of the conferences and to unite thermodynamics across Europe, the conferences changed their name in 2007 to Joint European Thermodynamics Conference, while the acronym remained the same.

Methods and concepts of equilibrium and non-equilibrium thermodynamics appear in various areas of physics, engineering, and life sciences. For this reason, JETC aims to improve the interaction among the different areas, and to pull together the different approaches to both the fundamental theoretical problems and to the applicative ones.

The following issues are within the focus of the conference, but papers on other relevant topics are of interest:

  • Solid mechanics and thermodynamics: Lagrangian vs. Eulerian approach, modeling of fractures, dislocations, anisotropy, memory, pre-stress, yield stress, damage, soft matter.
  • Thermodynamics and multiscale dynamics:  Thermodynamical characterization of instabilities/bifurcations in non-equilibrium systems, thermodynamic methods of reduction (e.g., from kinetic theory to fluid mechanics), memory effects.
  • Heat transfer and superfluids: Relations to superfluid models, one-component and two-component, vortex-filament method.
  • Computation of thermodynamic properties: Numerical simulation, Monte Carlo method and/or molecular dynamics.
  • Entropy and information: Construction of entropies, information theory and fluctuations.
  • Thermodynamics of diffusion and porous media: Theories of diffusion, thermodynamic restrictions and implications, non-Fickian diffusion, transport in porous media.
  • Mathematical methods of non-equilibrium thermodynamics: Exploitation of the entropy principle, parabolic vs. hyperbolic theories, existence and regularity of solutions, finite speed of signal propagation, Galilean invariance.
  • Thermodynamics and quantum physics: Two-state quantum heat engines, quantum ratchets and molecular Maxwell daemons.
  • Electrochemistry: Thermodynamic descriptions of electrochemical processes, electrodiffusion, electrochemical reactions.
  • Kinetics and dissipative structures: Reaction kinetics, self-organization and dissipative structures. 
  • Thermodynamics in social sciences: Thermodynamics in economy, biology, and medicine.
  • Thermodynamics and geometry: Geometric formulation of classical thermodynamic laws. 
  • Engineering thermodynamics: Applications of thermodynamics in engineering, machinery, aerodynamics, and chemical engineering.
  • Experimental thermodynamics: How to measure thermodynamic quantities; the construction of thermodynamic data sets.
  • Contribution of thermodynamics to efficiency and optimization: Sustainability and environment, finite-time thermodynamics, exergy, entropy production.
  • Non-equilibrium thermodynamics with applications to complex systems: Thermodynamical models to describe dissipative processes in complex media, such as superfluids, ionized fluid mixtures, polarizable and magnetizable media, crystals with defects, porous media, biosystems, semiconductors, nanosystems, metamaterials and others.

We consider an autonomous heat engine in simultaneous contact with a hot and a cold reservoir and describe it within a linear irreversible framework. In a tight-coupling approximation, the rate of entropy generation is effectively written in terms of a single thermal flux that is a homogeneous function of the hot and cold fluxes. The specific algebraic forms of the effective flux are deduced for scenarios containing internal and external irreversibilities for the typical example of a thermoelectric generator. Full article

The Kelvin relation, relating the Seebeck coefficient and the Peltier coefficient, is a theoretical basis of thermoelectricity. It was first derived by Kelvin using a quasi-thermodynamic approach. However, Kelvin’s approach was subjected to much criticism due to the rude neglect of irreversible factors. It was only later that a seemingly plausible proof of the Kelvin relation was given using the Onsager reciprocal relation with full consideration of irreversibility. Despite this, a critical issue remains. It is believed that the Seebeck and Peltier effects are thermodynamically reversible, and therefore, the Kelvin relation should also be independent of irreversibility. Kelvin’s quasi-thermodynamic approach, although seemingly irrational, may well have touched on the essence of thermoelectricity. To avoid Kelvin’s dilemma, this study conceives the physical scenarios of equilibrium thermodynamics to explore thermoelectricity. Unlike Kelvin’s quasi-thermodynamic approach, here, a completely reversible thermodynamic approach is used to establish the reciprocal relations of thermoelectricity, on the basis of which the Kelvin relation is once again derived. Moreover, a direct thermodynamic derivation of the Onsager reciprocal relations for fluxes defined as the time derivative of an extensive state variable is given using the method of equilibrium thermodynamics. The present theory can be extended to other coupled phenomena. Full article
