Control of mixing via entropy tracking
Physical Review E, 2010 We study mixing of isothermal fluids by controlling the global hydrodynamic entropy . In particular, based on the statistical coupling between the evolution of and the global viscous dissipation , we analyze stirring protocols such that ∼t(α)⇔∼t(α-1), with ...

Time and Entropy from Semi-classical Tunneling of the Cosmological Scale Function [PDF]
, 1995 Two major apparently unrelated problems, that of the origin of time in the universe associated with quantum gravity and to the entropy in de Sitter cosmological models, are found to have their origin in a single physical phenomenon: the semi-classical ...

Entropy vs. Majorization: What Determines Complexity?
Entropy, 2014 The evolution of a microcanonical statistical ensemble of states of isolated systems from order to disorder as determined by increasing entropy, is compared to an alternative evolution that is determined by mixing character.

Entropy, 2022 The statistical behaviours of different entropy generation mechanisms in the head-on interaction of turbulent premixed flames with a chemically inert wall within turbulent boundary layers have been analysed using Direct Numerical Simulation data.

Mixing k-Fold Independent Processes of Zero Entropy [PDF]
Proceedings of the American Mathematical Society, 1993 For each fixed k k we give a simple construction of a stochastic process ( X n ) ({X_n}) which is mixing, has zero entropy, and such that any k k -tuple of the X n {X_n} are ...

Materials & Design, 2019 The concept of the new category materials high entropy ceramics (HECs) has been proposed several years ago, which is directly borrowed from high entropy alloys (HEAs). It quickly attracts a lot of interests and displays promising properties.

A derivation of entropy of mixing [PDF]
Radiation Physics and Chemistry (1977), 1984 Abstract A simple method is proposed for obtaining the generally accepted formula of the concentration dependence of entropy in ideal solutions. The derivation, while implying a new definition of ideal mixtures, is independent both of macroscopic material properties and microscopic models.

The Gibbs Paradox: Lessons from Thermodynamics
Entropy, 2018 The Gibbs paradox in statistical mechanics is often taken to indicate that already in the classical domain particles should be treated as fundamentally indistinguishable.

Entropy, 2018 The Gibbs Paradox is essentially a set of open questions as to how sameness of gases or fluids (or masses, more generally) are to be treated in thermodynamics and statistical mechanics.

Entropy, 2023 In this work, the entropy generation analysis is extended to the multi-phase fluid flow within a Large Eddy Simulation (LES) framework. The selected study case consists of a generic selective catalytic reduction (SCR) configuration in which the water ...
