Turbulence

Turbulence or turbulent flow is violent, unsteady, chaotic movement of fluids like air and water. It is contrasted with laminar flow. Most motion of fluids in real life (outside laboratories) is turbulent.

Turbulence Media

• 

  The sky depicted in Vincent Van Gogh's 1889 painting, The Starry Night has been studied for its turbulent flow.

• 

  Laminar and turbulent water flow over the hull of a submarine. As the relative velocity of the water increases turbulence occurs.
