Parametric Study of a Gurney Flap Implementation in a DU91W(2)250 Airfoil
Energies, 2019 The growth in size and weight of wind turbines over the last years has led to the development of flow control devices, such as Gurney flaps (GFs). In the current work, a parametric study is presented to find the optimal GF length to improve the airfoil ...

A water tunnel study of Gurney flaps [PDF]
Several Gurney flap configurations were tested in the NASA Langley 16 x 24 inch Water Tunnel. These devices provided an increased region of attached flow on a wing upper surface relative to the wing without the flaps.

Effect of Deformable Gurney Flaps on the Output Power of Flapping Turbine
FluidsThe Gurney flap (GF) is a simple flat plate frequently mounted at the airfoil rear. Several investigations have been devoted to studying the effect of a rigid or even movable GF on the aerodynamic behavior of several devices such as flapping airfoils and
