A review of microstructure in concentrated suspensions and its implications for rheology and bulk flow

JF Morris - Rheologica acta, 2009 - Springer
An overview of present understanding of microstructure in flowing suspensions is provided.
An emphasis is placed on how the microstructure leads to observable bulk flow phenomena …

The hydrodynamics of confined dispersions

JW Swan, JF Brady - Journal of Fluid Mechanics, 2011 - cambridge.org
A method is proposed for computing the low-Reynolds-number hydrodynamic forces on
particles comprising a suspension confined by two parallel, no-slip walls. This is constructed …

X-ray radiography of viscous resuspension

B Saint-Michel, S Manneville, S Meeker, G Ovarlez… - Physics of …, 2019 - pubs.aip.org
We use X-ray imaging to study viscous resuspension. In a Taylor-Couette geometry, we
shear an initially settled layer of spherical glass particles immersed in a Newtonian fluid and …

The influence of secondary flows induced by normal stress differences on the shear-induced migration of particles in concentrated suspensions

A Ramachandran, DT Leighton - Journal of Fluid Mechanics, 2008 - cambridge.org
It was first demonstrated experimentally by H. Giesekus in 1965 that the second normal
stress difference in polymers can induce a secondary flow within the cross-section of a non …

Numerical simulation of particle migration in asymmetric bifurcation channel

GMY Ahmed, A Singh - Journal of non-newtonian fluid mechanics, 2011 - Elsevier
In this work we provide numerical validation of the particle migration during flow of
concentrated suspension in asymmetric T-junction bifurcation channel observed in a recent …

Mechanism for axial pattern formation of concentrated suspension in a horizontal rotating cylinder

S Konidena, B Vowinckel, R Seto… - Journal of Fluid …, 2024 - cambridge.org
We have performed numerical simulations to investigate the phenomenon of axial pattern
formation exhibited by a non-neutrally buoyant concentrated suspension. Continuum …

Mixing and segregation of microspheres in microchannel flows of mono-and bidispersed suspensions

C Gao, B Xu, JF Gilchrist - Physical Review E—Statistical, Nonlinear, and Soft …, 2009 - APS
We investigate the mixing and segregation of mono-and bidispersed microsphere
suspensions in microchannel flows. These flows are common in biological …

Microstructure of sheared monosized colloidal suspensions resulting from hydrodynamic and electrostatic interactions

B Xu, JF Gilchrist - The Journal of chemical physics, 2014 - pubs.aip.org
Hydrodynamic and near-particle interactions in sheared suspensions are communicated
through suspension microstructure to produce a wide variety of rheological behaviors. To …

The effect of gravity on the meniscus accumulation phenomenon in a tube

A Ramachandran, DT Leighton - Journal of Rheology, 2007 - pubs.aip.org
It is well known that when a suspension of noncolloidal, neutrally buoyant rigid particles is
drawn into an empty tube, the inward shear-induced migration of the particles results in a …

Single-fluid model of a mixture for laminar flows of highly concentrated suspensions

AA Gavrilov, AV Shebelev - Fluid Dynamics, 2018 - Springer
A model of laminar flow of a highly concentrated suspension is proposed. The model
includes the equation of motion for the mixture as a whole and the transport equation for the …
