“…By far, though the viscosity of multi-component molten salts has been studied by many researchers with experimental measurement and calculations [4][5][6][7][8][9][10], it is still insufficient to get good results from previous work due to high melting point and strict chemical conditions. Furthermore, the study on new compound salts is not far enough in elemental characteristic because of the high melting temperature and difficulties in measurement process.…”

In this paper several kinds of high temperature molten salts were investigated experimentally on viscosity-temperature characteristics with high-temperature viscometer. The viscosities of the molten salts were measured and compared with those from references to verify the reliability of the viscometer and measuring methods, and a good agreement was observed from the comparisons. Then, two new high-temperature molten salts were made from the HITEC salt by some additives and the viscosity-temperature profiles of them were obtained by experiments. The results show that the new molten salts have much lower viscosities, thus suitable for reducing the flow resistance in transportation system of high-temperature solar thermal power generation. high-temperature molten salts, viscosity, temperatureCitation: Chen Y C, Wu Y T, Ren N, et al.

“…Various empirical and semi‐empirical equations employed for predicting the viscosity of binary fluid solutions have been extended to multicomponent fluid systems (Pandey et al, 1994a; Martins et al, 2001; Shukla et al, 2006, 2007). In literature, some correlations describing quaternary systems are available for excess volume by Shukla et al (1989, 1988) and activity coefficients by Brostow and Sochnski (1975) but these correlations have at least two major defects.…”

Assuming a quaternary fluid solution to be made up of six binaries, a statistical approach of Flory has been extended to develop the expression for dynamic viscosity of multicomponent system using the concept of absolute rate and free volume approaches of liquid state. A reasonable agreement has been achieved between theory and the experiment for n-hexadecane + carbon tetrachloride + benzene + n-hexane quaternary system at 298.15 over a wide range of composition. An attempt has also been made to explain the nature of the molecular interactions, involved in the light of excess thermodynamic functions whose sign and magnitude depend upon the chain length and size of the component liquids.En supposant une solution de fluide quaternaire composée de six binaires, on a généralisé l'approche statistique de Flory dans le but d'établir l expression pour la viscosité dynamique du système multicomposantà l aide du concept de taux absolu et de l approche des volumes libres de l état liquide. Un accord raisonnable aété trouvé entre la théorie et l expérience pour le système quaternaire n-hexadécane + tétrachlorure de carbone + benzène + n-hexaneà 298,15 pour une vaste gamme de composition. On aégalement tenté d'expliquer la nature des interactions moléculaires, intervenantà la lumière des fonctions thermodynamiques d'excès dont le signe et la grandeur dépendent de la longueur de chaîne et de la quantité des composants liquides.
