Vorticity and
Vortex Dynamics
The simplest vortex loop is a circular vortex ring, which in a sense is a more
fundamental vortex structure than columnar vortices and can be easily produced
experimentally (e.g., by an impulsive motion of a piston), see Fig.4.22. Because
of ...

Vortex Methods and
Vortex Motion
Figure 4.16 shows vortex ring formation behind a delta wing in reverse, pitching
from 0° to 60° around the c/2 axis [49]. The vortex loop of the trailing edge vortex

Fluid Vortices: Fluid Mechanics and Its Applications
However, in a viscous flow, the presence of the no-slip condition together with the
induced velocity field of the ring will cause new vorticity to be generated along
the boundary. This vorticity, which is of opposite sense to that of the vortex ring, ...

VORTEX RING INTERACTION WITH A FREE SURFACE.
generated by the contaminant gradient. The distribution of the contaminant during the interaction depends on the strength of the contamination. Results are also compared to a collision with a no-slip surface.

Motion of an elliptic vortex ring is considered as an example of unsteady 3D
vortex motion. The Local Induction Equation is used for the analysis. By keeping
the self-induction constant and changing its value in the equation, different
features ...

Taylor [1953[ examined the properties of the uniform vortex ring formed by coarse
-graining the rolled up sheet into a circular vortex ring of radius R, core radius c,
and circulation P. The hydrodynamic impulse of the ring is F7r/?2. Assuming that
