WebApr 20, 2006 · The airfoil (NACA 0012 basic thickness form) was located in a wind tunnel, and the wake structure was measured using hot-wire sensors. The measurements of mean-velocity, turbulence intensity and Reynolds-stress components across the wake at several distances downstream show the complex nature of the near wake and its asymmetrical … Web2. The pressures around streamlined airfoil shapes are misleading. (we should use thin-wing models instead). If we put a cylinder in a wind tunnel, and adjust things for low Reynolds number (with no turbulence or flow-detachment), then we'll discover that the fluid pressure on the cylinder looks like this: sharepoint navigation bar

We can transform the local geometry of the cylinder into an ellipse, an airfoil, or a flat plate without influencing the geometry of the far-field flow. This procedure is known as conformal mapping. popcorn gadgets
