Abstract

An experiment of perpendicular Blade Vortex Interaction with an oscillating airfoil model has been set up and carried out. The use of the Particle Image Velocimetry allowed to see very interesting effects of the vortex induction. In particular, the combined effect of the vortex induction with the airfoil oscillation produces, in some conditions, a wide flow separation. This experiment indicates that also a perpendicular vortex can remarkably perturb the struck blade.
