Abstract : The stability and development of unsteady separation on airfoil leading edges has been investigated. In particular, attention was focused on investigations of 2D unsteady incompressible flow past a parabola at angle of attack which models the leading edge of many airfoils. This study has direct application to leading edge stall (LES) and thin airfoil stall as well as unsteady flow past leading edges. The general character of much of this study allows for application to other classes of unsteady boundary layer flow.
