Evolution of the nondimensional out-of-plane vorticity and in-plane velocity vectors for simplified bifurcation IAs with different and ; (upper row) and ; (middle row) and ; and (lower row) and at various time instants during the cycle: (a) , (b) , (c) , (d) , (e) , and (f) . R2 depicts the vortex ring in simplified bifurcation IAs and the green cross shows the location of the maximum -criteria on the midplane of IAs.
