The principal feature in the roll-up of the ligament is that the only stable configuration is that of a sphere. These data suggest that the growth of the instability and the resulting vortex roll-up is considerably stronger in the circular jet. The calculation proceeds smoothly until roll-up begins; inevitably the sheet crosses itself. To obtain a regular roll-up the vortices are uniformly spaced and given a sinusoidal perturbation of the appropriate wavelength. The result is the roll-up of the shear layer into vortical lumps one wavelength apart, connected by thin braids. In actual physical flows, a nonlinear roll-up of the vortex sheets occurs and the wake configuration is not known in advance. Both the roll-up and the coalescence of the vortices take place in a region, not at a single point. These data show that both the vortices accelerate after roll-up, then vortex 1 continues to accelerate but vortex 2 starts decelerating. The motion of the point vortices becomes chaotic in the region of the vortex sheet roll-up. This difference between the maximally unstable and the natural roll-up frequencies is being further investigated in our laboratory. We include in figure 2 a sequence of pictures showing the initial regular stages of roll-up of a vortex sheet. Two plateaus, one at the roll-up region and the other at the vortex merging region, existed. The apparent 'roll-up' of the streaklines is followed by their distortion and segregation during impingement upon the edge. It is available in a roll-up stick form. The roll-up of the shear layer is a mechanism for accumulation of vorticity in lumps. See all examples of roll up! These examples are from corpora and from sources on the web.
