Abstract
The unsteady flowfield above a NACA 0012 airfoil pitching under deep dynamic stall conditions has been investigated in a low-speed wind tunnel by means of Particle Image Velocimetry (PIV) mesurements and laser-sheet visualizations. The PIV results have beenfound to be of high quality, although velocity data were missing in some critical flow regions. A correct estimation of vortex distribution and out-of-plane velocity gradients could be determined.
