Computational results showing the evolution of the relative vorticity of vortex S at the time instances (a) 5 s, (b) 9 s, (c) 11 s, (d) 13 s, (e) 15 s, and (f) 17 s after the oar was lifted. The size of the window is about 12 cm square area. The solid lines represent the positive vorticity, while the dashed lines indicate the negative vorticity.
