Flow in Straight, Frictionless Containers

  • Marius Ungarish


Some fundamental phenomena of gravity and centrifugal separation of suspensions are readily illustrated by the flow field solution in the simple geometries considered in this chapter which are an idealization of the configurations introduced by Figs. 1.1.1 and 1.1.2. Sediment and/or pure fluid are collected by solid walls perpendicular to the body-force acceleration f * ; the other boundaries are assumed to be parallel to f * , far apart and frictionless. Exact solutions can be obtained by both the two-fluid and mixture models. Unless stated otherwise, we consider monodispersions, i.e., all the dispersed (spherical) particles are of equal radius a* and density ρ * D.
