Polydisperse suspensions consist of particles differing in size or density that are dispersed
in a viscous fluid. During sedimentation, the different particle species segregate and create …

Polydisperse suspensions with particles of a finite number N of size classes have been
widely studied in laboratory experiments. However, in most real-world applications the …

The settling of a bidisperse suspension with small particles having different sizes and
densities can be described by an initial value problem for a system of two non-linear, first …

The particle-based approach to sedimentation is extended to include velocity fluctuations
that result in hydrodynamic diffusion. The vector process describing the joint values of …

An exploratory computational study of the stability of tridisperse suspensions (in which
spheres of the same size have different densities) shows that dilute suspensions with all …

The random initial positions of particles in any sedimentation experiment and the extreme
sensitivity of the creeping-motion equations to even minute variations in these positions …

An effective voidage model of a liquid-fluidized bed that takes into account particle–particle
interaction has been used to predict the slip and interface velocities of sedimenting zones for …

There are two fundamentally different approaches to sedimentation and fluidization. The first
treats suspensions as continua while the second deals with individual particles. The first …

Continuum and particle-based methods are outlined and their features are contrasted. The
latter method is well suited to simulate small-scale laboratory experiments because the …
