Turbulence (or Turbulent Flow) is chaotic flow of a fluid. It is characterized by changes in flow velocity and pressure over space and time, and eddies, i.e., circular or swirling flows, often lasting only a short time.
Turbulence is in contrast to Laminar Flow in which fluid flows in continuous lines.
