rotational flow

[rō′tā·shən·əl ′flō]

(fluid mechanics)

Flow of a fluid in which the curl of the fluid velocity is not zero, so that each minute particle of fluid rotates about its own axis. Also known as rotational motion.

The time required for blending is reduced significantly by top-to-bottom flow compared with rotational flow. This angled mixer position is the most effective for mixing and blending applications and should be used in most situations that do not specifically involve drawing material from the surface.
