(Color online) Selected phases from jet centerline finding algorithm applied to FR case with p=1.25 kPa. Color denotes velocity magnitude and the black line is the calculated centerline position. Shown are examples of starting jet (left, phase ≈0.07 of one cycle), full jet (middle, phase ≈0.33), and decaying jet (right, phase ≈0.40). In the extreme sides of the images, potentially spurious vectors have been replaced with zero vectors.
