A Gibbs free energy minimization based model for liquid–liquid equilibrium calculation of a system containing oil, brine, and surfactant

open access: yesOil & Gas Science and Technology, 2020
Accurate and reliable phase equilibrium calculations of microemulsion systems are of great importance. This study deals with the thermodynamic modeling of Liquid–Liquid Equilibrium (LLE) of a system including oil (n-decane), brine (containing CaCl2 salt),

Thermodynamic resources in continuous-variable quantum systems

open access: yesnpj Quantum Information, 2021
Thermodynamic resources, beyond their well-known usefulness in work extraction and other thermodynamic tasks, are often important also in tasks that are not evidently thermodynamic.

Unified representation of homogeneous and quasi-homogenous systems in geometrothermodynamics

open access: yesPhysics Letters B, 2023
We analyze homogeneous and quasi-homogeneous thermodynamic systems within the formalism of geometrothermodynamics (GTD). A generalized Euler identity is used to obtain the explicit form of the three Legendre invariant metrics that are known in GTD for ...

Geometric description of BTZ black holes thermodynamics

open access: yes, 2008
We study the properties of the space of thermodynamic equilibrium states of the Ba\~nados-Teitelboim-Zanelli (BTZ) black hole in (2+1)-gravity.

A thermodynamically consistent kinetic framework for binary nucleation [PDF]

open access: yes, 2007
The traditional theory for binary homogeneous nucleation follows the classical derivation of the nucleation rate in the supposition of a hypothetical constrained-equilibrium distribution in the calculation of the cluster evaporation rate.

The Stumbling Block of the Gibbs Entropy: the Reality of the Negative Absolute Temperatures

open access: yesEPJ Web of Conferences, 2016
The second Tisza-Callen postulate of equilibrium thermodynamics states that for any system there exists a function of the system extensive parameters, called entropy, defined for all equilibrium states and having the property that the values assumed by ...

Thermalization of the system "3He-aerogel" at 1.5 K

open access: yes, 2010
At the present work we propose a new method for studying the processes of thermodynamic equilibrium setting in the adsorbed 3He film in a porous media. By this method we have studied the thermalization of the adsorbed 3He on the silica aerogel surface at

Thermodynamic stability of the stationary Lifshitz black hole of new massive gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In this paper we investigate the thermodynamic properties of the stationary Lifshitz black hole solution of New Massive Gravity. We study the thermodynamic stability from local and global point of view.

Nonlinear Non-Equilibrium Thermodynamics Based on the Ehrenfest–Klein Model

open access: yesEntropy, 2020
Nonlinear non-equilibrium thermodynamic relations have been constructed based on the generalized Ehrenfest−Klein model. Using these relations, the behavior of the entropy and its production in time at arbitrary deviations from equilibrium has been ...

Synthesis of Equilibrium and Non-Equilibrium Thermodynamics

open access: yesInternational Journal of Thermodynamics, 2021
The possibility of synthesis of equilibrium and non-equilibrium thermodynamics (thermostatics and thermokinetics) on classical principles as a deductive and phenomenological theory has been substantiated. This is achieved in the article on the basis of the law of conservation of energy due to its expression through the flows of the energy carrier and ...
