However, experimental data on several molten salt systems, of interest for various energy generation applications, are generally lacking. Physics-informed models, as well as molecular dynamic (MD) simulations, have the potential to populate gaps in current thermophysical property databases. Existing predictive models using MD simulation (Green–Kubo, non-equilibrium MD) take significantly longer to predict thermal conductivity than classical MD models that otherwise predict salt density with reasonable accuracy. We present an approach that uses the SuperSalt machine learning interatomic potentials (MLIPs) for chloride salts, as well as a structural coherence model (SCM) to predict thermal conductivity of molten salts using volumetric heat capacity, adiabatic speed of sound, and the partial pair distribution function. The SCM uses this function to predict the mean free path of thermal transport and applies generalized kinetic theory to predict thermal conductivity near the melting temperature, achieving results one to two orders of magnitude faster than existing MD methods. By also predicting the isothermal bulk modulus, the temperature dependence of thermal conductivity above the melting temperature can be determined. This integrated SCM-MLIP (ISM) methodology serves as a proof of concept for using MLIPs to predict thermal properties within current experimental uncertainties at a fraction of the computational cost. This enables investigation into thermal conductivity as well as other thermophysical properties across a variety of molten salt compositions. When coupled with targeted experimental studies, the ISM methodology can help contribute to existing databases necessary to safely implement molten salts into power generation systems.</p></div>","PeriodicalId":598,"journal":{"name":"International Journal of Thermophysics","volume":"47 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, surface tension measurements were conducted for pure liquid Al, pure liquid Si, and molten Al–Si alloys containing 5–80 at % Si using the oscillating drop method with electromagnetic levitation. Oxide-affected heating curves were excluded from the pyrometer calibration, and only oscillation data for which no oxide film was observed on the droplet surface were analyzed. For all examined compositions, the measured surface tension decreased linearly with increasing temperature. Near 1700 K, the surface tension decreased monotonically and nearly linearly with increasing Si concentration, and previously reported nonlinear behaviors, such as relatively high values in the Al-rich region and an increase toward the Si-rich side, were not observed. Uncertainty analysis confirmed that the nearly linear composition dependence was not due to measurement uncertainty. Butler equation calculations were performed using the pure-component surface tension values obtained in this study. The ideal-solution approximation reproduced the measured composition dependence and temperature coefficients more consistently than the subregular-solution calculation using the evaluated excess Gibbs energies.

The solubility increases with temperature and shows a pronounced non-monotonic dependence on solvent composition, reaching a maximum at an acetone mole fraction of 0.80, characteristic of co-solvency behavior. A clear solvation transition was observed: acetone preferentially solvates chrysin at intermediate compositions, whereas water dominates in both water-rich and acetone-rich regions. The solubility of chrysin was correlated using 11 thermodynamic models, classified into empirical/semi-empirical models, local-composition activity coefficient models, and COSMO–RS-based quantum chemical models. The Modified Apelblat and van’t Hoff equations showed the best performance. Thermodynamic analysis based on the van’t Hoff equation indicates that the dissolution process is endothermic and non-spontaneous, governed primarily by enthalpy.

In this study, the contact angles of CMAS melts on YSZ and Al₂O₃ substrates were measured using the sessile drop method to observe the effects of interfacial reactions on the wetting and spreading behaviors of CMAS melts. To elucidate the thermodynamics of the formation of Y-depleted ZrO₂ in CMAS melts, the saturation solubility of ZrO₂ in four different CMAS melts was measured. Sessile drop measurements and electron probe microanalyzer observations revealed that the contact angles of CMAS melts on the YSZ substrates continuously decreased owing to the progress of interfacial reaction, leading to the formation of Y-depleted ZrO₂. On the other hand, the contact angles of CMAS melts on the Al₂O₃ substrates remained constant because anorthite covered the entire interface and the local equilibrium at the interface was reached.
