Abstract
We consider the flow of a suspension in a rotating, cylindrical container with inclined endwalls and a dividing harrier that hlocks any azimuthal motion around the axis. A boundary layer of clarified fluid appears when the influence of the Coriolis force is counteracted and although a bulk swirling motion is prevented by the meridional section, there is still an appreciable azimuthal flow in this thin purified-fluid layer. This flux produces an even more intense current on the leading side of the barrier (relative to the rotation direction) where the section meets the inclined wall.Keywords
