The 'Brazil-nut effect' in bidisperse particle laden flow on an incline
Jack Luong, Sarah Cassie Burnett, Andrea L. Bertozzi
We study bidisperse suspensions -- suspensions where there are two particle species of the same density but different sizes -- of a viscous fluid on an incline. We use a lubricatio…

Equilibrium theory of bidensity particle-laden suspensions in thin-film flow down a spiral separator
Lingyun Ding, Sarah C. Burnett, Andrea L. Bertozzi
Spiral gravity separators are designed to separate multi-species slurry components based on differences in density and size. Previous studies have investigated steady-state solutio…

A comparative study of dynamic models for gravity-driven particle-laden flows
Wing Pok Lee, Jonathan D. Woo, Luke F. Triplett +4
The dynamics of viscous thin-film particle-laden flows down inclined surfaces are commonly modeled with one of two approaches: a diffusive flux model or a suspension balance model.…
