Nearly 70 years old, hydraulic fracturing is a core technique for stimulating hydrocarbon
production in a majority of oil and gas reservoirs. Complex fluids are implemented in nearly …

Abstract Systems made by particles in viscoelastic liquids are ubiquitous in a variety of
industrial and biological applications. Much work has been done in the last half-century in …

Experiments with the self-assembly of nanoparticles at liquid interfaces suggest that
cooperative and slow dynamical processes due to particle crowding at the interface govern …

Rigid particles suspended in viscoelastic fluids under shear can align in string-like structures
in the flow direction. Although this phenomenon was first reported almost four decades ago …

In this work, we extend the three-dimensional Smoothed Particle Hydrodynamics (SPH) non-
colloidal particulate model previously developed for Newtonian suspending media in …

Nanofluids have received much attention in part due to the range of properties possible with
different combinations of nanoparticles and base fluids. In this work, we measure the …

When particles are dispersed in a rheologically complex medium, a striking alignment of
particles into strings can be observed during shear flow. This occurs even under conditions …

This study focuses on the interaction of two small freely-moving spheres in a linear flow field
of yield stress fluids. We perform a series of experiments over a range of shear rates and …

The influence of particle-polymer interactions on the ensemble average stress is derived as
a function of the Deborah number for a dilute suspension of spheres in an Oldroyd-B fluid in …

Normal stress differences behavior of polymeric particle suspension in shear flow is
investigated. The first normal stress difference (N 1) in shear flow is found to mainly arise …
