Results of a blade-vortex interaction (BVI) study incorporating particle image velocimetry (PIV) are presented. Test cases encompass a variety of intersection geometries, including head-on parallel interactions. Results provide quantified flow visualization images of the flows generated during interactions. The deformation and division of the interaction vortex during head-on interactions are documented. In addition, secondary vortical structures generated during interactions are observed and their effect upon the interaction vortex is examined. All PIV results are examined in the light of understanding gained from previous pressure measurements made from the same BVI facility.
