Parameter study of active flow control on a high lift airfoil

Active manipulation of separated flows over airfoils at high angles of attack has been the focus of a number of investigations of many scientists and engineers in fluid mechanics. The objective of these investigations is to improve the aircraft aerodynamic performance by delaying the boundary layer separation. One of the main methods used in active flow control is the usage of blowing devices with constant and pulsed blowing. Through unsteady CFD simulation over an airfoil, this study highlights the impact of slot width, blowing momentum coefficient and jet velocity, in enhancing the aerodynamic characteristics of an airfoil.
