A vortex is a spiraling motion of material particles around a common center of rotation. Vortices are one of the most important research areas in fluid dynamics. This comes mainly from two facts. First, vortices have a great impact on the development of a flow in many cases. Second, although a colloquioal definition (as above) can be given, there exists no exact mathematical definition of a vortex, its extent or even its center. Thus, finding vortices is challenging an no method fitting for all situation exists.
Examples
Vortices in nature:
- Tornado
- Hurricane
- Wake vortex created at the tip of the wing of an aircraft
- Swirling water that runs thorugh the drain of a basin
