Fig 8. Flow structure at: (a) systole (0.25 ≲ t/T ≲ 0.31); (b) cycle-averaged state (0 ≤ t/T ≤ 1); (c) steady state with the Reynolds number at the systolic peak, Re = 651; (d) steady state at Re = 1000.

The velocity iso-surface thresholds are $1.9U_{\overline{cycle}}$, $1.1U_{\overline{cycle}}$, $1.9U_{\overline{cycle}}$, and $2.9U_{\overline{cycle}}$, respectively.
