Figure 2


Fig. 2. Schematic diagram of a fin positioned normal to uniform flow showing drag producing `cross-flow bluff-body drag' vortices. These are formed as the angle of attack of the fin increases well above 0°. The 90° situation is shown. The rolling and pitching motion of the fin helps retain the vortices over the fin, thereby delaying stall and enhancing lift due to the low pressures in their cores.
