WebAug 19, 2008 · A computational study of separated flows over a NACA 0012 airfoil at transitional Reynolds numbers is performed. The transitional nature of the flowfield is incorporated into the computations through \dY-Reθ transition model based on local variables. ... Application of Divergent Trailing-Edge Airfoil Technology to the Design of … Webthe pressure, lift, and drag changes that occurred with the use of the Divergent Trailing Edge (DTE) device reported by Hemme [8]. The modified trailing edges used in that study were very much like a Gurney flap, with the high pressure side filled in with a concave ramp. Hemme stated that the DTE acted like a Gurney flap on a high-speed ...

Aerodynamic Optimization of Airfoils Using Adaptive …

WebAs seen above, PARSEC method faces lack of control on trailing edge modeling, to overcome this, Sobieczky proposed a way to give trailing edge a concave shape. Lower … WebThe similarity parameters for a rigid airfoil with an extended trailing edge are considered. The similarity parameters for a rigid airfoil are Reynolds number Rec =U∞c/ν and Mach number M∞, where U∞ is the freestream velocity and c is the airfoil chord. Since an extended trailing edge is attached to the rigid airfoil, additional similarity http://pubs.sciepub.com/ajme/2/4/1/ gao staff directory
