Specialty Definition: Turbulence

DomainDefinition

Aerospace

A state of fluid flow in which the instantaneous velocities exhibit irregular and apparently random fluctuations so that in practice only statistical properties can be recognized and subjected to analysis. Compare laminar flow.These fluctuations often constitute major deformations of the flow and are capable of transporting momentum, energy, and suspended matter at rates far in excess of the rate of transport by the molecular processes of diffusion and conduction in a nonturbulent or laminar flow. (references)

Specialty Definition: Turbulence

(From Wikipedia, the free Encyclopedia)

Turbulence or Turbulent flow is a flow regime characterized by low momentum diffusion, high momentum convection, and pressure and velocity variation with time. It is opposed by laminar flow. The (dimensionless) Reynolds number characterizes whether flow conditions lead to laminar or turbulent flow.

Examples of turbulence

Anecdote: a famous scientist was asked what he would ask God, given the opportunity. His laconic reply was: "Why turbulence?"
