Abstract
In this paper we review simulation methods, which address suspension flows at different length scales. Taking the multiscale problem of confined suspension flow in fractionation and sorting applications as a guiding example, we discuss these numerical methods for use in a multiscale simulation framework. We have classified the methods in terms of dimensionless numbers, governing the physics of confined suspension flows, and the resolution of particles on the computation grid. From our literature review, we conclude, that for suspension flows at Peclet numbers larger than unity, Lattice Boltzmann is a good method to implement for all levels of the multiscale simulation framework.
