WebApplied to the flow past a circular cylinder placed at the origin, the Joukowski mapping can be used to produce the flow past a flat plate. This is, of course, the most elemental representation of an airfoil. For a flat plate of chordlength c = 2 a we choose the mapping constant and the radius of the cylinder to both be a /2. WebThe solution of the flow around a circular cylinder with circulation in a cross flow can be used to predict the flow around thin airfoils. 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.
