Vortex
A vortex is a turbulent flow which resembles a tornado. Or, maybe it is better to say that a tornado is a well known example of a large vortex. A vortex is also formed as water goes down a drain, as in a sink or a toilet.
Examples
- Lift (force) of a wing (which relates to the aspect ratio of the wing).
- The primary cause of drag in the sail of a sloop
- Sunspot
- Tornado
- Whirlpool[?]
