Flow of a Self-Similar Non-Newtonian Fluid Using Fractal Dimensions

open access: yesFractal and Fractional, 2022
In this paper, the study of the fully developed flow of a self-similar (fractal) power-law fluid is presented. The rheological way of behaving of the fluid is modeled utilizing the Ostwald–de Waele relationship (covering shear-thinning, Newtonian and ...

Shear-thinning and shear-thickening emulsions in shear flows [PDF]

open access: yesPhysics of Fluids, 2021
We study the rheology of a two-fluid emulsion in semiconcentrated conditions; the solute is Newtonian while the solvent is an inelastic power-law fluid. The problem at hand is tackled by means of direct numerical simulations using the volume of fluid method.

Rheological characteristics analysis of shear thickening fluids based on response surface methodology

open access: yesMaterials Research Express, 2022
This paper analyzed the influence of various components and the external environment on the rheological properties of shear thickening fluid (STF). The single-factor experimental study was carried out with the silica particle size, the mass fraction of ...

Effect of Surface Roughness on the Rheology of Silica-Coated Styrene/Acrylic Acid Copolymer Suspensions [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2023
Hypothesis: Today, due to the widespread use of coarse particle suspensions in chemical industry, the tendency to study the rheological behaviour of suspensions has increased significantly.

Discontinuous shear thickening in concentrated suspensions. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci, 2019
The flow of concentrated suspensions of solid particles can be suddenly blocked by the formation of a percolated network of frictional contacts above a critical value of the applied stress. Suspensions of magnetic particles coated with a superplastifier molecule were shown to produce a strong jamming transition. We find that, for these suspensions with

Discontinuous shear thickening in Brownian suspensions [PDF]

open access: yesPhysical Review E, 2018
Discontinuous shear-thickening in dense suspensions naturally emerges from the activation of frictional forces by shear flow in non-Brownian systems close to jamming. Yet, this physical picture is incomplete as most experiments study soft colloidal particles subject to thermal fluctuations.

Shear effects in thickening [PDF]

open access: yesProceedings of the International Seminar on Paste and Thickened Tailings, 2010
One-dimensional computational dewatering models which account for the influence of networked particulate bed compression, have enabled accurate predictions of dewatering in sedimentation, centrifugation and filtration processes in both the laboratory and industry.

Shear thickening in densely packed suspensions of spheres and rods confined to few layers [PDF]

open access: yes, 2010
We investigate confined shear thickening suspensions for which the sample thickness is comparable to the particle dimensions. Rheometry measurements are presented for densely packed suspensions of spheres and rods with aspect ratios 6 and 9.

Rheology and Microstructure of Shear Thickening Fluid Suspoemulsions

open access: yesApplied Rheology, 2014
A novel shear thickening suspoemulsion is formulated and studied with a new rheo-microscope instrument. The experimental fluid system is comprised of a immiscible blend of Newtonian, low molecular weight poly(dimethylsiloxane) and a shear thickening ...

Characterization and performance analysis of a shear thickening fluid damper

open access: yesMeasurement + Control, 2019
Shear thickening fluid is a smart material with rheological properties that can be rapidly varied by excitation changes. To fully explore the advantages of using shear thickening fluid in various devices, a phenomenological model for simulating complex ...
