Thermodynamically-Consistent Modeling of Ferromagnetic Hysteresis

open access: yesMaterials, 2023
Models of ferromagnetic hysteresis are established by following a thermodynamic approach. The class of constitutive properties is required to obey the second law, expressed by the Clausius–Duhem inequality, and the Euclidean invariance. While the second law states that the entropy production is non-negative for every admissible thermodynamic process ...

Bayesian quantification of thermodynamic uncertainties in dense gas flows [PDF]

open access: yes, 2014
A Bayesian inference methodology is developed for calibrating complex equations of state used in numerical fluid flow solvers. Precisely, the input parameters of three equations of state commonly used for modeling the thermodynamic behavior of so-called ...

Thermodynamic substantiation of ecological-physiological modeling [PDF]

open access: yesBIO Web of Conferences
The forest ecosystem is a classical example of an open system. Its behavior can only be described within the framework of nonequilibrium thermodynamics. The fundamental concept of thermodynamics is the entropy of a system.

Beyond heat baths II: Framework for generalized thermodynamic resource theories [PDF]

open access: yes, 2018
Thermodynamics, which describes vast systems, has been reconciled with small scales, relevant to single-molecule experiments, in resource theories. Resource theories have been used to model exchanges of energy and information.

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),

Comprehensive Thermodynamic Evaluation of the Natural Gas-Fired Allam Cycle at Full Load

open access: yesEnergies, 2023
In this study, thermodynamic modeling and simulations were used to optimize the design point performance of the Allam cycle. The topic fits perfectly with the strategies for power sector decarbonization toward net zero emission.

Thermodynamic Description of Ternary Fe-B-X Systems. Part 8: Fe-B-Mo, with Extension to Quaternary Fe-B-Cr-Mo System [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
Thermodynamic optimizations of the ternary Fe-B-Mo system and its binary sub-system B-Mo are presented. The Fe-B-Mo description is then extended to the quaternary Fe-B-Cr-Mo system by assessing the ternary B-Cr-Mo system.

Constraints of Compound Systems: Prerequisites for Thermodynamic Modeling Based on Shannon Entropy

open access: yesEntropy, 2014
Thermodynamic modeling of extensive systems usually implicitly assumes the additivity of entropy. Furthermore, if this modeling is based on the concept of Shannon entropy, additivity of the latter function must also be guaranteed.
