# Vortical

Vortical

"Vortical" means pertaining to a vortex or to vortices. In fluid dynamics, the movement of a fluid can be said to be vortical if the fluid moves around in a circle, or in a helix, or if it tends to spin around some axis. Such motion can also be called solenoidal.

Vortical movement is characterized by non-zero curl:

:$operatorname\left\{curl\right\} mathbf\left\{v\right\} e 0,$where v is the velocity vector field of the fluid.

The curl of the velocity (at a specified point of the vector field) yields a vector which points in the direction around which the fluid is rotating.
