Description of a Water Tank and of Initial Low Reynolds Number Flow and Buoyant Free Model Tests

Abstract

A water tank was designed and constructed at the University of Florida to visualize low Reynolds number flows. Static or drain-down test conditions may be used, the former for observation of the free movement of positively or negatively buoyant models. The tank is 4' x 4' horizontal dimensions, and its square test section is six feet high; it is constructed entirely of Plexiglas and therefore is corrosion free. The maximum unit Reynolds number in the drain-down mode is 10,000/in. Photographs of flow about the Basic Finner model from preliminary tests are included. Buoyant sphere trajectories were observed in preliminary trials to be planar or spiral depending upon Reynolds number.
