TL;DR: In this article, an experimental technique for evaluation of wettability of ceramic particulate with liquid metal was developed, where threshold pressures for infiltration can either be used as quantitative measure of wetablity or be converted to wetting angles by using the capillary force equation.
Abstract: An experimental technique for evaluation of wettability of ceramic particulate with liquid metal was developed. Wettability tests were conducted by pressure infiltration through uniformly packed powder specimens. The threshold pressures for infiltration can either be used as quantitative measure of wettablity or be converted to wetting angles by using the capillary force equation. With this technique, wettability was measured for SiC and B4C particulates with liquid aluminum alloys. The effects of temperature, time, and alloying element on wettabilty were investigated. Theoretical calculations of solid-liquid interfacial energy were also reviewed briefly. 61 references.

TL;DR: In this article, the relative merits of using molten salts or ionic liquids as electrolytes for liquid metal cells and the choice of electrode materials are discussed, and an overview of investigations on magnetohydrodynamic instabilities in liquid metal batteries, namely the Tayler instability and electromagnetically excited gravity waves are presented.
Abstract: Liquid metal batteries are possible candidates for massive and economically feasible large-scale stationary storage and as such could be key components of future energy systems based mainly or exclusively on intermittent renewable electricity sources. The completely liquid interior of liquid metal batteries and the high current densities give rise to a multitude of fluid flow phenomena that will primarily influence the operation of future large cells, but might be important for today's smaller cells as well. The paper at hand starts with a discussion of the relative merits of using molten salts or ionic liquids as electrolytes for liquid metal cells and touches the choice of electrode materials. This excursus into electrochemistry is followed by an overview of investigations on magnetohydrodynamic instabilities in liquid metal batteries, namely the Tayler instability and electromagnetically excited gravity waves. A section on electro-vortex flows complements the discussion of flow phenomena. Focus of the flow related investigations lies on the integrity of the electrolyte layer and related critical parameters.

TL;DR: In this paper, a flat bubble column with rectangular cross-section was measured by particle tracking velocimetry, and simultaneous measurements of void fraction by using high frame rate neutron radiography and four-sensor probe were also performed to observe the bubble-probe interaction.
Abstract: Liquid metal two-phase flows in metallic vessels were studied by using high frame-rate neutron radiography. Both a bubble column and a gas-lift loop arrangement have been considered. Liquid velocity field of two-phase flow in a flat bubble column with rectangular cross-section was measured precisely by the particle tracking velocimetry. In a gas-lift loop, simultaneous measurements of void fraction by using high frame-rate neutron radiography and four-sensor probe were also performed to observe the bubble-probe interaction. Asymmetric Abel inversion was applied to compare the radial void fraction profiles. Measured radial void fraction profiles obtained by neutron radiography and electrical conductivity probe agreed well with each other. From these measurements, the measurement error and basic characteristics of gas–liquid metal two-phase flow were clarified.

TL;DR: In this article, the sessile drop technique has been used to measure the contact angle of liquid metals and liquid alloys in contact with polycrystalline alumina, and the linear temperature functions of the work of adhesion as well as of the interfacial energy were also determined in the investigated systems.
Abstract: The sessile drop technique has been used to measure the contact angle of liquid metals and liquid alloys in contact with polycrystalline alumina. The experiments were carried out in argon atmosphere at various temperatures. The measured contact angles exhibit no wettability (θ > 90°). The linear temperature functions of the work of adhesion as well as of the interfacial energy were also determined in the investigated systems. The partial high values of the work of adhesion in several Al2O3-liquid metal systems can be attributed to a chemical bond establishment at the interface. The values of the interfacial energies at the melting point of the metals, for non-reactive Al2O3-liquid metal systems, vary in a restricted region (2·35–2·75) J m−2). An empirical relation is proposed for evaluation of the interfacial energy of the metals at their melting point. The agreement between experimental and calculated values is satisfactory.

TL;DR: In this paper, the electron distribution around an ion in liquid metals has been derived from the difference in structure factors determined by X-ray and neutron-diffraction methods with the help of a theoretical calculation of the electron-electron correlation function.
Abstract: Electron distribution in liquid metals and charge transfer in liquid alloys are qualitatively and quantitatively discussed in terms of the structure factors and the thermodynamic quantities obtained experimentally. The electron distribution around an ion in liquid metals has been derived from the difference in structure factors determined by X-ray and neutron-diffraction methods with the help of a theoretical calculation of the electron–electron correlation function. Charge transfer in liquid alloys is also estimated by using the partial structure factors in the long-wavelength limit and the Thomas–Fermi screening theory. The charge-transfer effect in liquid alloys is also verified by the measurements of partial structure factors and magnetic susceptibilities.
