摘要：

The effects of leading-edge cylinder rotation on the boundary layer and wake, and lift-to-drag ratio of a NACA 0015 airfoil, were quantified. With cylinder rotation, a delayed boundary-layer flow separation accompanied by a narrowed wake and an enhanced lift could be obtained. As such, the boundary-layer momentum thickness decreased with increasing cylinder rotation and grew linearly with the stremwise distance along the airfoil surface. The given measurement not only demonstrate the improved aerodynamic performance through a leading-edge circulation control device, but also provide typical data for computer model validations.
