## Figures

Figure 1

Aft section of wind tunnel. 1—test contour, 2—vortex generator, 3—roof of wind tunnel; dimensions in mm.

Figure 2

Streamwise surface pressure distribution for nonmanipulated boundary layer. Reynolds number referred to the cylinder radius R. Open symbol 엯: R=680mm; remaining symbols R=500mm. Symbols 엯 and ● correspond to the same flow velocity: V=19.1m∕s.

Figure 3

Tooth vortex generator (a), streamwise surface pressure distribution R=500mm (b), and 680mm (c). w∕h=10, q=ρV2∕2; symbol 엯: (SCR)—singular semi-circular rod across the flow.
