/vor·tex/ (vor´teks) pl. vor´tices   [L.] a whorled or spiral arrangement or pattern, as of muscle fibers, or of the ridges or hairs of the skin.

vortex

pl. vortexes, vortices
Etymology: L, whirl
a whirlpool effect produced by the whirling of a more or less cylindric mass of fluid (liquid or gas). The velocity of the motion increases as the radius of the circle described by the motion decreases; the velocity decreases as the radius increases. Tornadoes and whirlpools are examples of free vortexes.

ver·ti·cil

(vĕr'ti-sil)
A collection of similar parts radiating from a common axis.
Synonym(s): vortex (1) , whorl (4) .
[L. verticillus, the whirl of a spindle, dim. of vertex, a whirl]

vor·tex len·tis

(vōr'teks len'tis)
One of the stellar figures on the surface of the lens of the eye.
Synonym(s): vortex (3) .

whorl

(wŏrl)
1. A turn of the spiral cochlea of the ear.
2. Synonym(s): vortex of heart.
3. A turn of a concha nasalis.
4. Synonym(s): verticil.
5. An area of hair growing in a radial manner suggesting whirling or twisting.
Synonym(s): vortex (2) .
6. One of the distinguishing patterns in the Galton system of classification of fingerprints.

2), the wall shear can be expressed from the axial component of the curl of vorticity as
Resultant changes to wavenumber are not shown, but as can be seen by the magnitude of the divergence and shear, the rays which encounter the highest vorticity regions will have the largest changes in wavenumber.
The researchers performed extensive scour analysis using various combinations of equations for resultant velocity and critical velocity to determine the empirical adjustment factor to account for turbulence and vorticity at the upstream corner of the culvert.

The model presented here suggests that the early-formed Fl and F2 folds are also drag folds that have undergone progressive tightening and reorientation toward the flow direction, while simultaneously being refolded by F3 folds developing parallel to the vorticity axis of a non-coaxial shear.
At the outer and upper edges of the computational domain, the perturbation temperature, perturbation pressure, and windward component of vorticity are set to zero.
The reverse process--the generation of counterclockwise vorticity and downslope transport of it--appears in the off-shelf phase of the tidal current.
