This paper deals with the long-standing conflict between interpretations of thermoelectricity based on original reversible thermodynamics Thomson and later irreversible Onsager. It is shown that, by a slight modification Maxwellian relaxation treated in previous [J. Goddard K. Kamrin, “Dissipation potentials from elastic collapse,” Proc. R. Soc. A 475, 20190144 (2019)], Onsager's symmetry simpl...

Thermodynamics is the branch of science that deals with the conversion of one form of energy into another. The laws of thermodynamics govern all materials processes and reactions and can be used to predict how a system and its surroundings will behave under various defined conditions. Changes in temperature (T), pressure (p), and volume (V) all play a role in the overall thermodynamic behavior ...

In this work, we investigate the validity of axioms such as Onsager Reciprocal Relations (ORR) for heat transfer in irreversible thermodynamics close to equilibrium. We show that ORR case could be directly derived by introducing widely accepted concept coefficients into entropy production rate and assuming thermal conductivity are uniquely defined. It is believed work can not only used pedagogi...

We show that active transport processes in biological systems can be understood through a local equilibrium description formulated at the mesoscale, the scale to describe stochastic process. This new approach uses the method established by nonequilibrium thermodynamics to account for the irreversible processes occurring at this scale and provides nonlinear kinetic equations for the rates in ter...

The thermodynamics of an electrically charged, multicomponent continuous medium with electromagnetic fields is analysed in the non-relativistic limit. Applying locally the first and second law of thermodynamics and Maxwell’s equations for a linear theory of electromagnetism, three equations characterising the continuous medium are derived: a thermostatic equilibrium equation, a reversible and a...

Abstract. We discuss the structure and main features of the nonlinear evolution equation proposed by this author as the fundamental dynamical law within the framework of Quantum Thermodynamics. The nonlinear equation generates a dynamical group providing a unique deterministic description of irreversible, conservative relaxation towards equilibrium from any non-equilibrium state, and satisfies ...

The performances of solar cells and thermoelectricmaterials are governed by thermodynamics. The material properties of these have temperature dependence due to thermal expansions of lattices and an effect of electron–phonon coupling etc. The temperature-dependent energy levels has been included in statisticalmechanics, naturally requiring a rectification of the second law of thermodynamics with...

A GENERAL principle of virtual dissipation in irreversible thermodynamics is applied to a solid under initial stress with small non-isothermal incremental deformations and coupled thermomolecular diffusion and chemical reactions. Dynamical field and Lagrangian equations are obtained directly by variational procedures. In addition, the treatment embodies new fundamental concepts and methods in t...

in this study, the performance of an irreversible regenerative brayton cycle is sought through power maximizations using finite-time thermodynamic concept in finite-size components. optimizations are performed using a genetic algorithm. in order to take into account the finite-time and finite-size concepts in the current problem, a dimensionless mass-flow rate parameter is used to deploy time v...

In recent work a class of quasi port Hamiltonian system expressing the first and second principle of thermodynamics as a structural property has been defined: Irreversible port-Hamiltonian system. These systems are very much like port-Hamiltonian systems but differ in that their structure matrices are modulated by a non-linear function that precisely expresses the irreversibility of the system....
