Sažetak

OpisDrag sphere nasa.svg	English: Drag coefficient C_d for a sphere as a function of Reynolds number Re, as obtained from laboratory experiments. The solid line is for a sphere with a smooth surface, while the dashed line is for the case of a rough surface. The numbers along the line indicate several flow regimes and associated changes in the drag coefficient: 2: attached flow (Stokes flow) and steady separated flow, 3: separated unsteady flow, having a laminar boundary layer upstream of the separation, and producing a vortex street, 4: separated unsteady flow with a laminar boundary layer at upstream side, before flow separation, with downstream of the sphere a chaotic turbulent wake, 5: post-critical separated flow, with a turbulent boundary layer.
