On the combined use of Vortex Generators and Gurney Flaps for turbine airfoils. In: Journal of Physics: Conference Series. The Science of Making Torque from Wind (TORQUE) conference 2022, 1-3 Jun 2022, Delft, the Netherlands. doi: 10.1088/1742-6596/2265/3/032040


While Vortex Generators (VGs) and Gurney Flaps (GFs) are commonly used for airfoil flow control, studies of a combination of the two devices are rare. The present investigation aims at examining the combined effect of VGs and GFs on a 20% thick airfoil. To this end, a wind tunnel investigation coupled with a computational study was performed. The present paper presents force, pressure and Stereo Particle Image Velocimetry measurements, along with Unsteady Reynolds Averaged Navier Stokes simulations.
