  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.

Examples of turbulence in a Sentence

  1. Megan Vanderves:

    I would describe the experience as kind of extreme turbulence on an airplane but louder, and there was kind of a lot of smoke smell. The first thought I really had when I woke up was,' Oh my God we're derailing,' it was probably 10 or 15 seconds of rocking back and forth and tons of noise, and then we came to a stop. Really we didn't know what was going on for a couple minutes.

  2. Brian Rehling:

    In our minds it was the correct decision. The inflation data does not support a rate hike at this time. You throw in some of the global turbulence and (that) supports the decision to leave rates unchanged.

  3. United Airlines:

    Air Wisconsin Flight 3833 operating as United Express from Charlottesville, Va. to Washington Dulles International encountered turbulence because of high winds, a few customers onboard the regional jet became ill as the aircraft was preparing to land. The aircraft landed safely and taxied to its gate. No customers required medical attention because of the turbulence.

  4. United Airlines:

    The flight encountered turbulence while traveling from Newark to Honolulu, and a few passengers and flight attendants sustained injuries. Our primary focus is helping our passengers and crew, and our flight safety team will review what happened.

  5. Robbi Gaharu:

    I thought maybe it was caused by turbulence. After 10 minutes in Lion Air the plane dropped as if it was losing power. People panicked. It dropped about 400 feet.
