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)].

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.

A Photon Force and Flow for Dissipative Structuring: Application to Pigments, Plants and Ecosystems

open access: yesEntropy, 2022
Through a modern derivation of Planck’s formula for the entropy of an arbitrary beam of photons, we derive a general expression for entropy production due to the irreversible process of the absorption of an arbitrary incident photon spectrum in material ...

The Role of Vegetation on the Ecosystem Radiative Entropy Budget and Trends Along Ecological Succession

open access: yesEntropy, 2014
Ecosystem entropy production is predicted to increase along ecological succession and approach a state of maximum entropy production, but few studies have bridged the gap between theory and data.

Radiative entropy production [PDF]

open access: yesAIAA Journal, 1985
The radiative tensor obtained from the specular moments of the transfer equation is considered. The radiative entropy production is expressed in terms of this tensor.

Optimizing Our Patients’ Entropy Production as Therapy? Hypotheses Originating from the Physics of Physiology

open access: yesEntropy, 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 ...

Quantifying the thermodynamic entropy budget of the land surface: is this useful? [PDF]

open access: yesEarth System Dynamics, 2011
As a system is moved away from a state of thermodynamic equilibrium, spatial and temporal heterogeneity is induced. A possible methodology to assess these impacts is to examine the thermodynamic entropy budget and assess the role of entropy production ...

Analysis of Hydraulic Losses in Vortex Rope Inside the Draft Tube of Francis Pump-Turbine Based on Entropy Production Theory

open access: yesMachines, 2023
The existence of vortex ropes inside the draft tube significantly impacts hydraulic efficiency and operational stability, and few studies on the formation mechanism of vortex ropes and hydraulic loss problems have been explored.
