Microstructural smoothed particle hydrodynamics model and simulations of discontinuous shear-thickening fluids [PDF]

The Physics of Fluids, 2023
Despite the recent interest in the discontinuous shear-thickening (DST) behavior, few computational works tackle the rich hydrodynamics of these fluids. In this work, we present the first implementation of a microstructural DST model in smoothed particle

Vortex-induced vibrations of a cylinder in inelastic shear-thinning and shear-thickening fluids

Journal of Fluid Mechanics, 2022
Vortex-induced vibrations (VIV) of a cylinder in a Newtonian fluid is a model problem in fluid–structure interactions and has been studied extensively. In this work, we study the influence of shear-thinning and shear-thickening fluids on the VIV response

An empirical equation for shear viscosity of shear thickening fluids

Journal of Molecular Liquids, 2021
Quantitative modelling of the rheology of non-Newtonian fluids requires significant empirical input due to very complex behaviour of the bulk fluid as a result of particle-scale physics of fluids.

A phenomenological theory-based viscosity model for shear thickening fluids

Materials Research Express, 2022
A viscosity model for shear thickening fluids (STFs) based on phenomenological theory is proposed. The model considers three characteristic regions of the typical material properties of STFs: a shear thinning region at low shear rates, followed by a ...

Microstructure and thickening of dense suspensions under extensional and shear flows [PDF]

, 2017
Dense suspensions are non-Newtonian fluids which exhibit strong shear thickening and normal stress differences. Using numerical simulation of extensional and shear flows, we investigate how rheological properties are determined by the microstructure ...

Generality of shear thickening in suspensions [PDF]

, 2010
Suspensions are of wide interest and form the basis for many smart fluids. For most suspensions, the viscosity decreases with increasing shear rate, i.e. they shear thin. Few are reported to do the opposite, i.e.

Material removal characteristics of magnetic-field enhanced shear thickening polishing technology

Journal of Materials Research and Technology, 2021
To achieve the efficient and high-quality machining of hard and brittle ceramics used in various industries, in addition to other materials that are difficult to process, a magnetic-field enhanced shear thickening polishing technology was developed in ...

The shear-driven Rayleigh problem for generalised Newtonian fluids [PDF]

, 2014
We consider a variant of the classical ‘Rayleigh problem’ (‘Stokes’s first problem’) in which a semi-infinite region of initially quiescent fluid is mobilised by a shear stress applied suddenly to its boundary. We show that self-similar solutions for the

Effects of variable magnetic field and partial slips on the dynamics of Sutterby nanofluid due to biaxially exponential and nonlinear stretchable sheets

Heliyon, 2023
Based on both the characteristics of shear thinning and shear thickening fluids, the Sutterby fluid has various applications in engineering and industrial fields.

Features of the power-law fluid over cylinders in a channel via gap aspects: Galerkin finite element method (GFEM)-based study

Frontiers in Physics, 2023
The goal of this investigation is to carry out a comprehensive analysis of hydrodynamic forces, with particular attention being paid to the power-law fluid flow across cylinders and presence gap considerations.
