Turbulence

Describes fluid motion disturbed from its average behaviour by random fluctuations over a range of temporal and spatial scales.

These fluctuations often constitute major deformations of the flow and are capable of transporting:

The transportation rates can be far in excess of the rate of transport by the molecular processes of diffusion and conduction in a nonturbulent or laminar flow.
