GEOMETRY MODIFICATION EFFECTS ON A JUNCTION VORTEX FLOW

The three-dimensional flow around hull protrusions such as control surfaces, struts, or sails is characterized by a junction vortex system. Influence or control of such a junction vortex system can be important in homogenizing the downstream flow that may encounter other control surfaces or a propeller disc. The effects of geometry modifications on some properties of time-resolved flow measurements on the upstream symmetry plane of a junction vortex region were studied. Six different cases were considered including a reference case with no geometry changes. A large triangular fillet appeared to be most effective in significantly reducing the integrated turbulent kinetic energy.
