Turbulence

In fluid dynamics, turbulence or turbulent flow is fluid motion exhibiting chaotic changes in pressure and flow velocity. It is in contrast to laminar flow, which occurs when a fluid flows in parallel
Laminar and turbulent water flow over the hull of a submarine. As the relative velocity of the water increases, turbulence occurs.

Flow visualization of a turbulent jet, made by laser-induced fluorescence. The jet exhibits a wide range of length scales, an important characteristic of turbulent flows.
The plume from this candle flame goes from laminar to turbulent. The Reynolds number can be used to predict where this transition will take place
