Bayesian quantification of thermodynamic uncertainties in dense gas flows [PDF]
, 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 properties of a simple, confining model [PDF]
, 1997 We study the equilibrium thermodynamics of a simple, confining, DSE-model of 2-flavour QCD at finite temperature and chemical potential. The model has two phases: one characterised by confinement and dynamical chiral symmetry breaking; and the other by ...

Differentiable thermodynamic modeling
Scripta Materialia, 2022 A new framework of thermodynamic modeling is proposed by introducing the concept of differentiable programming, where all the thermodynamic observables including both thermochemical quantities and phase equilibria can be differentiated with respect to the underlying model parameters, thus allowing the models learned by gradient-based optimization.

Thermodynamically-Consistent Modeling of Ferromagnetic Hysteresis
Materials, 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 ...

Numerical Evaluation of Biochar Production Performance of Downdraft Gasifier by Thermodynamic Model
Energies, 2022 A theoretical evaluation of the biochar production process using a biomass gasifier has been carried out herein. Being distinguished from the previous research trend examining the use of a biomass gasifier, which has been focused on energy efficiency ...

The Establishment of Thermodynamic Model for Ti Bearing Steel-Slag Reaction and Discuss
Frontiers in Materials, 2022 A thermodynamic model for seven CaO-MgO-BaO-CaF2-SiO2-Al2O3-TiO2 ladle slags based on the Ion and Molecule Coexistence theory (IMCT) is establishment and validated by the experiment results at 1873K. The calculated activity of SiO2, Al2O3 and TiO2 in the

Thermodynamic Modelling of an Ejector with Compressible Flow by a One-Dimensional Approach
Entropy, 2012 The purpose of this study is the dimensioning of the cylindrical mixing chamber of a compressible fluid ejector used in particular in sugar refineries for degraded vapor re‑compression at the calandria exit, during the evaporation phase. The method used,

A thermodynamically consistent phase-field model for two-phase flows with thermocapillary effects [PDF]
, 2014 In this paper, we develop a phase-field model for binary incompressible (quasi-incompressible) fluid with thermocapillary effects, which allows for the different properties (densities, viscosities and heat conductivities) of each component while ...
