1. Three-dimensional vortical structure visualized by the iso-surfaces of the q criterion for inviscid (left column) and viscous (Re=4000) (middle column) simulations at t=5 ms (A), 21 ms (B), 41 ms (C) and 71 ms (D).
Three-dimensional vortical structure visualized by the iso-surfaces of the q criterion for inviscid (left column) and viscous (Re=4000) (middle column) simulations at t=5 ms (A), 21 ms (B), 41 ms (C) and 71 ms (D). The skeleton of different vortical structures marked on the left are plotted in the right column and distinguished with different colors according to the color legend. Vortical structures created by the fins and the tail are denoted by F1–F4 and T1–T3, respectively. See supplementary material Movies 1 and 2 for 3-D movies of the wake structure of the inviscid and viscous simulations.
