Figure 6.

Three planes for case 8, where ${\theta }_{T,o}=3.63$ and ${\theta }_{C,o}\approx 0$, are shown here. Body (and sting) generated vortices between the body and the caudal fin are visualized using two-dimensional Q-criterion (Q) contours ($Q=[1,5,20,50]s^{-2}$). (A) midspan plane (0 mm). (B) $+20$ mm plane. (C) $+40$ mm plane.
