VISUALIZATION OF BOUNDARY-LAYERS IN A SECTIONED CENTRIFUGE

We are interested in the flow of a suspension in a rotating, conical cavity with a dividing barrier that blocks any azimuthal motion around the axis. In order to simplify the experiment, the flow of a homogeneous fluid, slightly denser than the bulk fluid filling the container, has been used. The theoretical predictions of a previous paper have been tested, in particular those relating to the intense current on the dividing barrier that was found. This current has been visualized. A quantitative comparison between theory and experiment is made. The qualitative findings of the theory that apply to this experiment are completely verified. The quantitative agreement is fair. © 1990 Birkhäuser Verlag.
