| Résumé | Several axi-symmetric surfaces or revolution are introduced as possible cowlings to be attached to an existing spherical buoy to create a streamlined buoy shape that minimizes the drag force and reduces vortex shedding whilst the buoy remains stable and self-aligning in tidal flows. Analysis of the proposed shapes is carried out by CFD software and a proposed shape is found that reduces the drag force to 25% of that of the original spherical buoy. As well, analysis of data from an axi-symmetric airship Akron is performed to investigate lift, drag, pitching moment, pressure distributions and centers of effort of surfaces of revolution as functions of angle of attack. |
