Local equilibrium and the second law of thermodynamics for irreversible systems with thermodynamic inertia [PDF]

, 2015
Validity of local equilibrium has been questioned for non-equilibrium systems which are characterized by delayed response. In particular, for systems with non-zero thermodynamic inertia, the assumption of local equilibrium leads to negative values of the

Thermodynamics for non-equilibrium pattern formation

AIP Advances, 2011
The second entropy theory for non-equilibrium thermodynamics is used to show that the optimum structure or pattern of a time-dependent system corresponds to the maximum entropy. A formula for the total entropy of convective heat flow is derived.

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

Entropy, 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

Entropy, 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 ...

Comment on 'Non-equilibrium thermodynamics of light absorption' [PDF]

, 2002
A recent paper by Meszéna and Westerhoff (1999 J. Phys. A: Math. Gen. 32 301) has aimed to address what is referred to as a principal question of biological thermodynamics, the possibility of describing photosynthesis in terms of non-equilibrium ...

Non-equilibrium modifications of the nuclear equation of state [PDF]

, 1996
Non-equilibrium modifications of the nuclear equation of state are assessed in the framework of Extended Irreversible Thermodynamics. The expected size of the non-equilibrium corrections to quantities like the nuclear-matter incompressibility $K$ and the

Exploring quantum thermodynamics with NMR

Journal 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.

On universal features of the turbulent cascade in terms of non-equilibrium thermodynamics [PDF]

Journal of Fluid Mechanics, 2017
Features of the turbulent cascade are investigated for various datasets from three different turbulent flows, namely free jets as well as wake flows of a regular grid and a cylinder.
