Wind tunnel testing of an airfoil with a moving surface boundary-layer control.

摘要

he control of boundary layer is very important in the field of aerodynamics and hydrodynamics and becomes essential for current wing design technology to increase lift, stalling angle of attack and lift-to-drag ratio. Therefore, an experimental investigation has been conducted on a two-dimensional airfoil, NACA 0024, equipped with a moving surface to control the boundary layer. The moving surface, which is the surface of a rotating cylinder, is located at the leading edge of the airfoil. The airfoil was tested for different values of
