The Entropy of the Universe and the Maximum Entropy Production Principle [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2013
The dominant mode of entropy production enabled by the large-scale technological systems that power the world economy is the degradation of chemical energy in fossil fuels. One key parameter determining the rates of fossil fuel consumption and entropy production is the price of energy. The Rayleigh-Benard cell provides a laboratory analog in which, for

Foraging Dynamics and Entropy Production in a Simulated Proto-Cell

open access: yesEntropy, 2022
All organisms depend on a supply of energetic resources to power behavior and the irreversible entropy-producing processes that sustain them. Dissipative structure theory has often been a source of inspiration for better understanding the thermodynamics ...

A review on Thermodynamics in Water Cycle with Emphasizing on Entropy and Maximum Entropy Production Principle [PDF]

open access: yesعلوم و مهندسی آب و فاضلاب, 2022
Hydrological cycle is directed into thermodynamic non-equilibrium state and maximum entropy production through thermodynamic processes. Therefore, it is possible to understand and describe hydrological cycle through computation of entropy production rate

Entropy Production and the Maximum Entropy of the Universe [PDF]

open access: yesThe 5th International Electronic Conference on Entropy and Its Applications, 2019
The entropy of the observable universe has been calculated as Suni ~ 10104 k and is dominated by the entropy of supermassive black holes. Irreversible processes in the universe can only happen if there is an entropy gap ΔS between the entropy of the observable universe Suni and its maximum entropy Smax: ΔS = Smax − Suni.

The Maximum Entropy Production Principle: Its Theoretical Foundations and Applications to the Earth System [PDF]

open access: yes, 2010
The Maximum Entropy Production (MEP) principle has been remarkably successful in producing accurate predictions for non-equilibrium states. We argue that this is because the MEP principle is an effective inference procedure that produces the best ...

A radiative-convective model based on constrained maximum entropy production [PDF]

open access: yesEarth System Dynamics, 2019
The representation of atmospheric convection induced by radiative forcing is a long-standing question mainly because turbulence plays a key role in the transport of energy as sensible heat, geopotential, and latent heat. Recent works have tried using the

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 ...

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.
