Sedimentation of small particles

Although sedimentation can be considered as one of the simplest
examples of suspension flow, much remains unknown about the
fundamental properties of sedimenting suspensions. The problem that
one encounters lies in the long range nature of the multibody
hydrodynamic interactions between particles. This will be illustrated
for sedimenting suspensions of spheres, of non-spherical particles
such as fibers, and for sedimenting clouds of particles.
