Gurney flap—Lift enhancement, mechanisms and applications
Progress in Aerospace Sciences, 2008Abstract Since its invention by a race car driver Dan Gurney in 1960s, the Gurney flap has been used to enhance the aerodynamics performance of subsonic and supercritical airfoils, high-lift devices and delta wings. In order to take stock of recent research and development of Gurney flap, we have carried out a review of the characteristics and ...

Numerical investigation into energy extraction of flapping airfoil with Gurney flaps
Energy, 2016Abstract A new type of Gurney flap is applied for energy extraction enhancement of a flapping airfoil. Two-dimensional Navier-Stokes simulations at Re = 10 4 are conducted to study the effect of Gurney flaps with various heights. The investigations are undertaken over a wide range of kinematic parameters (reduced frequency k , pitching amplitude
