Two approaches to the wave-number dependent viscosity n(q) of liquid metal Rb are compared. The first is based on the two-component theory of a liquid metal, and expresses n(q) in terms of the ionic static structure factor S(q) plus elastic scattering data. The second describes the ion...

Viscosity is an important property which could determine the flow liquid metal characteristics and reflect the liquidus structure. Therefore, the existence of an accurate model is necessary to calibrate the experimental measurement value of viscosity. At present, many models have been proposed to ...

The viscosity coefficient entering sound wave attenuation is evaluated for the liquid alkali metals in an ion-electron plasma approach. It is shown that the contribution from electrical conduction, though small, is by no means negligible. The calculated longitudinal viscosity is very close to the mea...
On the theoretical side, such data would provide further information towards the understanding of the liquid state, while, in the field of applied metallurgy, the viscous nature of liquids is tied closely with the flow behaviour of metals in filling moulds. The paucity of data in these fields ...
The rotational measurement technique has been developed to measure the dynamic viscosity of liquid metals. A special procedure is accomplished to eliminate both end and eccentricity effects. The technique was calibrated and tested with liquids of known rheology. The apparent viscosity of low melting all...
Here we present dynamical first-principles simulations of liquid iron which indicate that the viscosity of iron at core temperatures and pressures is at the low end of the range of previous estimates - roughly 10 times that of typical liquid metals at ambient pressure. This estimate supports the...
An electron-ion plasma model is used to calculate the longitudinal viscosity of liquid alkali metals. The electronic contribution to the viscosity is found to be vanishingly small. The final result is obtained in terms of the viscosity of a classical one-component plasma. The results are in bett...
Shear viscosity of liquid Sn–Ag, Sn–Cu and Sn–Ag–Cu eutectics from melting temperature up to 1100K and their electrical conductivity and thermoelectric power up to 850K have been investigated. The electrical properties of liquid Sn with additions of Fe and Ni have also been studied. It ...
