Entropy, 2020 Understanding how nature drives entropy production offers novel insights regarding patient care. Whilst energy is always preserved and energy gradients irreversibly dissipate (thus producing entropy), increasing evidence suggests that they do so in the ...

Entropy Production in Exactly Solvable Systems [PDF]
Entropy, 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.

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

The entropy production for thermal operations [PDF]
Scientific 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)].

On the Irreversible Production of Entropy [PDF]
Reviews 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 ...

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 ...

Free and classical entropy over the circle. [PDF]
, 2007 Relative entropy with respect to normalized arclength measure on the circle is greater than or equal to the negative logarithmic energy (Voiculescu's negative free entropy) and is greater than or equal to the modified relative free entropy.
