Figure 2: (a) Flow state diagram in Wi–BR state space. Coloured symbols represent different steady and time-dependent flow states depicted to the right, as indicated by corresponding symbols: (b) low-Wi ‘symmetric’ state (BR = 0.2, Wi = 9.5); (c) ‘laterally asymmetric’ state (BR = 0.2, Wi = 43); (d) ‘upstream bending streamlines’ (BR = 0.48, Wi = 53); (e) ‘upstream wall vortices’ (BR = 0.48, Wi = 82); (f) ‘time-dependent laterally asymmetric’ state (BR = 0.1, Wi = 257); (g) ‘asymmetric jetting’ (BR = 0.2, Wi = 384); (h) ‘time-dependent upstream wall vortices’ (BR = 0.44, Wi = 160); (i) ‘upstream cylinder vortex’ (BR = 0.48, Wi = 481).
