  1. Turbulence, Turbulencynoun

    Etymology: turbulence, Fr. turbulentia, Latin.

    I have dream’d
    Of bloody turbulence; and this whole night
    Hath nothing been but forms of slaughter. William Shakespeare.

    Oft-times noxious where they light
    On man, beast, plant, wasteful and turbulent,
    Like turbulencies in the affairs of men,
    Over whose heads they roar, and seem to point:
    They oft foresignify and threaten ill. John Milton.

    I come to calm thy turbulence of mind,
    If reason will resume her sov’reign sway. Dryden.

    You think this turbulence of blood,
    From stagnating preserves the flood,
    Which thus fermenting by degrees,
    Exalts the spirits, sinks the lees. Jonathan Swift.

  1. Turbulence

    In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers.Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent.: 2  Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This increases the energy needed to pump fluid through a pipe. The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping in a fluid flow. However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence create a very complex phenomenon. Richard Feynman described turbulence as the most important unsolved problem in classical physics.The turbulence intensity affects many fields, for examples fish ecology, air pollution, precipitation, and climate change.

  1. turbulence

    Turbulence refers to a chaotic or irregular motion of air or fluid characterized by fluctuations or eddies. It is often unpredictable and can occur in various phenomena such as weather patterns, airplane flights, river flows, and systems beyond the Earth's atmosphere. Turbulence can cause rapid changes in pressure and velocity.

Webster Dictionary

  1. Turbulencenoun

  1. Turbulence

    In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic and stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and time. Nobel Laureate Richard Feynman described turbulence as "the most important unsolved problem of classical physics." Flow in which the kinetic energy dies out due to the action of fluid molecular viscosity is called laminar flow. While there is no theorem relating the non-dimensional Reynolds number to turbulence, flows at Reynolds numbers larger than 5000 are typically turbulent, while those at low Reynolds numbers usually remain laminar. In Poiseuille flow, for example, turbulence can first be sustained if the Reynolds number is larger than a critical value of about 2040; moreover, the turbulence is generally interspersed with laminar flow until a larger Reynolds number of about 4000. In turbulent flow, unsteady vortices appear on many scales and interact with each other. Drag due to boundary layer skin friction increases. The structure and location of boundary layer separation often changes, sometimes resulting in a reduction of overall drag. Although laminar-turbulent transition is not governed by Reynolds number, the same transition occurs if the size of the object is gradually increased, or the viscosity of the fluid is decreased, or if the density of the fluid is increased.
