Entropy Production in Exactly Solvable Systems

open access: yesEntropy, 2020
The rate of entropy production by a stochastic process quantifies how far it is from thermodynamic equilibrium. Equivalently, entropy production captures the degree to which global detailed balance and time-reversal symmetry are broken.

Entropy Production of Run-and-Tumble Particles [PDF]

open access: yesEntropy
We analyze the entropy production in run-and-tumble models. After presenting the general formalism in the framework of the Fokker–Planck equations in one space dimension, we derive some known exact results in simple physical situations (free run-and ...

Cavitation Characteristics and Structure Optimization of Two-Dimensional Valve Based on Entropy Production Theory [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
In addition to noise and vibration, cavitation also lowers the efficiency, performance, and working lives of two-dimensional valves. To study the effect of cavitation on the flow characteristics of two-dimensional valves, standard  turbulence model and ...

Analysis of flow loss characteristics of slanted axial-flow pump device based on entropy production theory

open access: yesRoyal Society Open Science, 2022
Slanted axial-flow pump devices are widely applied in urban water supply, irrigation and drainage engineering fields. The second law of thermodynamics is applied to investigate the flow loss characteristics of the 30° slanted axial-flow pump model ...

The entropy production for thermal operations [PDF]

open access: yesScientific Reports, 2020
AbstractAccording to the first and second laws of thermodynamics and the definitions of work and heat, microscopic expressions for the non-equilibrium entropy production have been achieved. Recently, a redefinition of heat has been presented in [Nature Communications volume 8, Article number: 2180 (2017)].

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory

open access: yesEnergies, 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 ...

On the Irreversible Production of Entropy [PDF]

open access: yesReviews of Modern Physics, 1948
The importance of irreversible entropy production is emphasized. The first and second laws of thermodynamics are both expressed by equalities by giving due recognition to the irreversible production of entropy. By specialization and combination of these equations, an "efficiency equation" is derived, applicable to cyclical and steady-state processes ...

Entropy Production in Quantum is Different [PDF]

open access: yesEntropy, 2019
Currently, ‘time’ does not play any essential role in quantum information theory. In this sense, quantum information theory is underdeveloped similarly to how quantum physics was underdeveloped before Erwin Schrödinger introduced his famous equation for the evolution of a quantum wave function.
