摘要：
Experimental measurements of the viscosity of molten salts nanofluid containing multi-walled carbon nanotubes were performed for a wide range of the shear rate and various nanotube concentrations. In addition, the effect of nanoparticle aggregation is also investigated in the present study. The high temperature nanofluid showed the non-Newtonian behavior in low shear rate region but it was extended to high shear rate region by increasing the nanoparticle concentration. The viscosity of the nanofluid is significantly enhanced up to 93% in the concentration of 2 wt%. The results are well matched with the Krieger-Dougherty equation using a nanoparticle aggregation factor. (C) 2014 Elsevier B.V. All rights reserved.
