We investigate the effects of fiber aspect ratio, roughness, flexibility, and volume fraction on
the rheology of concentrated suspensions in a steady shear flow using direct numerical …

Two colloidal suspensions of paucidisperse, spherical silica particles with different surface
chemistries leading to extreme limits of surface contact friction are studied to identify …

The processing of dense suspensions is a crucial step in many industries including mining;
the production of ceramics; and the manufacture of pharmaceuticals. It is widely reported …

A typical dense non-Brownian particulate suspension exhibits shear thinning (decreasing
viscosity) at low shear rate or stress followed by a Newtonian plateau (constant viscosity) at …

We propose a constitutive model to predict the viscosity of fiber suspensions, which
undergoes shear thinning, at various volume fractions, aspect ratios, and shear …

Material extrusion is an additive manufacturing technique that enables the creation of
reproducible and complex hardware by depositing a viscous, shear-thinning ink onto a …

The measurement of yield stress and shear thinning flow behavior of slurries formed from
unpretreated corn stover at solids loadings of 100–300 g/L provides a key metric for the …

The rheology of suspensions showing discontinuous shear thickening (DST) is well
documented in conventional rheometer with rotating tools, but their study in capillary flow is …

The irreversible behaviour of a highly confined non-Brownian suspension of spherical
particles at low Reynolds number in a Newtonian fluid is studied experimentally and …

While significant progress has been made in the modeling and simulation of uniform fiber
suspensions, no existing model has been validated for industrially-relevant concentrated …
