Entropy and Entropy Production in Multiscale Dynamics [PDF]
Journal of Non-Equilibrium Thermodynamics, 2019 Abstract Heat conduction is investigated on three levels: equilibrium, Fourier, and Cattaneo. The Fourier level is either the point of departure for investigating the approach to equilibrium or the final stage in the investigation of the approach from the Cattaneo level.

Entropy and entropy production in some applications [PDF]
Physica A: Statistical Mechanics and its Applications, 2014 By using entropy and entropy production, we calculate the steady flux of some phenomena. The method we use is a competition method, $S_S/ + ={\it maximum}$, where $S_S$ is system entropy, $ $ is entropy production and $ $ is microscopic interaction time. System entropy is calculated from the equilibrium state by studying the flux fluctuations.

Measurement of Stochastic Entropy Production [PDF]
Physical Review Letters, 2006 Using fluorescence spectroscopy we directly measure entropy production of a single two-level system realized experimentally as an optically driven defect center in diamond. We exploit a recent suggestion to define entropy on the level of a single stochastic trajectory (Seifert, Phys. Rev. Lett. {\bf 95}, 040602 (2005)).

Entropy production by resonance decays [PDF]
Physical Review C, 1996 We investigate entropy production for an expanding system of particles and resonances with isospin symmetry -- in our case pions and $ $ mesons -- within the framework of relativistic kinetic theory. A cascade code to simulate the kinetic equations is developed and results for entropy production and particle spectra are presented.

Thermodynamics of Thermoelectric Phenomena and Applications [PDF]
Entropy, 2011 Fifty years ago, the optimization of thermoelectric devices was analyzed by considering the relation between optimal performances and local entropy production. Entropy is produced by the irreversible processes in thermoelectric devices.

Physical Review Research, 2020 We show a relation between the entropy production in stochastic thermodynamics and the stochastic interaction in the integrated information theory. To clarify this relation, we introduce an information-geometric interpretation of the entropy production ...

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory
Energies, 2022 A regulating valve is a key control element in the coal liquefaction industry, whose flow field distribution is related to the entropy production. In order to make a quantitative evaluation of the energy loss in the cavitation flow and calculate the ...
