Fig. 7

Comparison of wake vortex sheet strength for an aspect ratio 4 wing oscillating at $k=0.5$. The ULLT results show only the wake model assumed in the outer domain. Since the wing is shrunk to a line in the outer domain of the ULLTs, the x coordinate of the trailing edge, $x_{\mathrm{te}}$, is zero for ULLTs. Shown at t mod $2\pi /\omega =0$
