▪ Abstract We review the fluid mechanics and rheology of dense suspensions, emphasizing
investigations of microstructure and total stress.“Dense” or “highly concentrated” …

Particle migration in nanofluids has received less than due attention in the literature, and is
generally an open research topic requiring more investigation. Particle migration can have …

Pressure-driven flow of a noncolloidal suspension is studied in two-dimensional channel
and axisymmetric circular pipe geometries at bulk solids fractions of 0.2≤ ϕ≤ 0.5. Flows are …

We investigate in detail the problem of confined pressure-driven laminar flow of neutrally
buoyant non-Brownian suspensions using a frictional rheology based on the recent …

The complex rheological behaviour of suspensions is very strongly affected by the details of
the microstructure and the interparticle forces by which it is controlled. The difficulties …

Flow of a semidilute neutrally buoyant and non-colloidal suspension is numerically studied
in the Taylor–Couette geometry where the inner cylinder is rotating and the outer one is …

The flow of concentrated suspensions is well known to be accompanied by irreversible bulk
migrations. One approach to modeling the migration of particles relative to the bulk motion is …

We harness the physics-informed neural network (PINN) approach to extend the utility of
phenomenological models for particle migration in shear flow. Specifically, we propose to …

We review existing mixture models for shear-induced migration (SIM) in flowing viscous,
concentrated particle suspensions via an analysis of the models from the perspective of a …

This paper addresses the modeling of the phenomenon of particle migration in the flow of
monodispersed non-colloidal suspensions at neglected inertia using the Suspension …
