Cylinder airfoil

WebThe lift on a spinning cylinder has been clearly demonstrated, and its discussion includes a vortex in the circulating air. Many discussions of airfoil lift invoke such a vortex in the effective circulation of air around the moving airfoil. WebFour cylinder-airfoil configuration parameters were evaluated: the gap G/D and offset z/D distances between the cylinder and airfoil, the cylinder-diameter-to-airfoil-chord ratio D/c, and the cylinder cross-sectional geometry. During the investigation of each parameter, the airfoil angle of attack varied from α= -5 to 40 while the Reynolds ...
