Schematic of an axisymmetric cylinder with radial shape variation viewed as a cross-section along the Z-axis. The “perimeter” eddy paths – discussed in the Results and Discussion section – are mapped out in grey with the direction of the eddies indicated by the curved arrows. The larger arrows indicate the overall direction of EOF. The perturbation wavelength is L and the invariant radius of the channel away from the constriction region is a0.
