  1. Of, or pertaining to a vortex; containing vortices


Extensive Definition

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\ \mathbf \ne 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.
