This paper compares theory and experiment for the kinetics of time-dependent sedimentation. We discuss noninteracting (apart from hydrodynamic interaction) suspensions and colloids which may exhibit behavior similar to the one-dimensional motion of compressible gas. The velocity of sedimentation (or creaming) depends upon the volume fraction of the constituting particles and leads to Burgers-like equations for concentration profiles. It is shown that even the bidispersive system of two coupled…

A review of settling at low Peclét number, where Brownian fluctuations are dominant, aims to show that a lot more can be learnt both from the sedimentation equilibrium and from the particle settling dynamics of a wide class of systems, ranging from simple colloids to mesogenic suspensions.

Comparison of the LBM with the modified local Crank-Nicolson method solution of transient one-dimensional nonlinear Burgers' equation

This paper solves the transient one-dimensional nonlinear Burgers' equation using the lattice Boltzmann method and shows that at higher Reynolds numbers the accuracy of the LBM is higher than the MLCN method and vice versa.
