The 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
visualisation images of the flows generated near the
blade tip and inboard during interactions. PIV
results are examined in the light of understanding
gained from previous pressure measurements made from
the same BVI facility. Both the difficulties and the
advantages of utilising the PIV technique in this
application are discussed.
