The aqueous solution of polymer shows non-Newtonian behavior and its apparent viscosity is function of polymer concentration, shear rate, temperature, etc. (Nasr-El-Din et al. 1992).
Rheological results exhibited pseudoplastic or shear thinning flow behavior, where its viscosity decreased with increasing shear rate.
All silk formic acid solutions exhibited almost Newtonian fluid behavior and the viscosity increased with increasing sericin content.
Viscosity measurements showed that the nanofluids demonstrated Newtonian behavior and the viscosity of the nanofluids depended strongly on the tested temperatures and the nanoparticles loadings.
By colloidal processing aqueous suspensions with 25 vol% solids content, pH 10, 1 wt% deffloculant and 0.2 wt% binder exhibited shear thinning behavior and apparent viscosity suitable for replica method.
Interestingly, the blend also showed strong shear thinning behavior and a viscosity that is almost an order of magnitude lower than the starting PC resin.
As shown in the figure, the viscosity of water remained almost constant with an increase in the shear rate, indicating Newtonian behavior, and the viscosity of all the NCBNFs decreased with an increase in the shear rate, indicating non-Newtonian and shear-thinning behavior.
This paper presents an experimental study on the rheological behavior and viscosity reduction of heavy crude oil and its blends to improve the pipeline transportation by using a Haake RS6000 rheometer and a lab scale flow loop.
The iron-phosphorus based bulk metallic glass forming alloy Fe67Mo6Ni3.5Cr3.5P12C5.5B2.5 is characterized with respect to its thermophysical properties, crystallization and relaxation behavior, as well as its viscosity.
The model considers the interaction between elastohydrodynamic behavior and viscosity temperature effect.
