Calculation of the Entropy Balance Equation in a Non-equilibrium Reaction-diffusion System
Entropy, 2010 In this article, we discuss the relationships between thermodynamic quantities and the spatial pattern in a reaction-diffusion model based on the reversible Gray-Scott model.

Entropy production in random billiards
Discrete & Continuous Dynamical Systems - A, 2021 We introduce a class of random mechanical systems called random billiards to study the problem of quantifying the irreversibility of nonequilibrium macroscopic systems. In a random billiard model, a point particle evolves by free motion through the interior of a spatial domain, and reflects according to a reflection operator, specified in the model by ...

Numerical investigation of entropy generation of turbulent flow in twisted tri-lobed tubes
Case Studies in Thermal Engineering, 2023 Twisted tri-lobed tubes have garnered attention due to their exceptional heat transfer efficiency and straightforward fabrication. Existing literature lacks comprehensive assessments of the overall heat transfer performance of twisted tri-lobed tubes ...

Fluctuation Theorem for Hidden Entropy Production
, 2012 In the general process of eliminating dynamic variables in Markovian models, there exists a difference in the irreversible entropy production between the original and reduced dynamics. We call this difference the hidden entropy production, since it is an

Entropy production in systems with long range interactions
, 2017 On a fine grained scale the Gibbs entropy of an isolated system remains constant throughout its dynamical evolution. This is a consequence of Liouville's theorem for Hamiltonian systems and appears to contradict the second law of thermodynamics.

Bacterial chemotaxis and entropy production [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2010 Entropy production is calculated for bacterial chemotaxis in the case of a migrating band of bacteria in a capillary tube. It is found that the speed of the migrating band is a decreasing function of the starting concentration of the metabolizable attractant.

On the validity of entropy production principles for linear electrical circuits
, 2007 We discuss the validity of close-to-equilibrium entropy production principles in the context of linear electrical circuits. Both the minimum and the maximum entropy production principle are understood within dynamical fluctuation theory.

Entropy Production of Main-Sequence Stars
Entropy, 2015 The entropy production (inside the volume bounded by a photosphere) of main-sequence stars is calculated based on B–V photometry data. The entropy-production distribution function and the dependences of entropy production on temperature and luminosity ...
