Vortex

For other uses, see Vortex (disambiguation).

A vortex (pl. vortices) is a spinning, often turbulent, flow of fluid. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the fluid are greatest at the center and become smaller with distance from the center.
