In fluid dynamics, turbulent flow is characterized by the irregular movement of particles (one can say chaotic) of the fluid.In contrast to laminar flow the fluid does not flow in parallel layers, the lateral mixing is very high, and there is a disruption between the layers. Turbulence is also characterized by recirculation, eddies, and apparent randomness.
