Influence of Spherical and Pyramidical Dimples and Bumps on Airfoil Performance in Subsonic Flow

In this study, surface features such as dimples and bumps are introduced to the surface of a NACA 0012 airfoil to study their effect on boundary layer separation, particularly at high angles of attack. Six modified airfoils were designed with dimples and bumps of spherical and pyramidical shapes. A...
