The case studied is the flow field over a subsonic airfoil with four suction and injection slots on the suction side of the airfoil. Five different angles of attack, 0, 5, 10, 13.3 and 20 with the Mach ... drag reduction, lift enhancement and flow-induced noise suppression. By controlling the flow, the fuel ... skin-friction drag for a laminar ... Center for Turbulence Research Annual Research Briefs 2010 ... Skin-friction drag reduction has significant practical value for marine vehicles. It is known that skin-friction drag accounts for more than 60% of the total drag of a cargo ship. For several decades, various methods have been explored to reduce the skin-friction drag. Polymer/riblet combination for hydrodynamic skin friction ... injecting a drag reducing polymer into the individual groove valleys at multiple points along each groove such that amounts of the polymer needed to reduce skin friction along the entire length of the surface are minimized, infecting the drag reducing polymer by means of an array of slots or holes angled such that the injected polymer is ...

Skin Friction Drag. Definition. Friction Drag, also known as Skin Friction Drag, is drag caused by the friction of a fluid against the surface of an object that is moving through it. It is directly proportional to the area of the surface in contact with the fluid and increases with the square of the velocity.
