In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow, which occurs when a fluid flows in parallel layers with no disruption between those layers. [1]
TURBULENCE definition: 1. a state of confusion without any order: 2. strong sudden movements within air or water: 3. a…. Learn more.
Mar 3, 2023 · In air travel, turbulence is a certainty and a major source of flight anxiety for flyers of all stripes. But understanding what causes turbulence, where it occurs, and the high-tech tools...
Oct 16, 2020 · Turbulence is defined as the 'irregular motion' of the air from eddies and vertical airflows. It is different from wind that flows horizontally from different directions, a force that is easily measured by weather services. A turbulent flow can occur when the wind changes directions or a storm arrives at a locality.
: the quality or state of being turbulent: such as. a. : great commotion or agitation. emotional turbulence. b. : irregular atmospheric motion especially when characterized by up-and-down currents. c. : departure in a fluid from a smooth flow. Examples of turbulence in a Sentence. The plane hit quite a bit of turbulence during our flight.
Jul 9, 2024 · Turbulence, In fluid mechanics, a flow condition (see turbulent flow) in which local speed and pressure change unpredictably as an average flow is maintained. Common examples are wind and water swirling around obstructions, or fast flow (Reynolds number greater than 2,100) of any sort.
In this course, we will cover fundamental aspects of turbulence—Kolmogorov’s theory of turbulence in spectral and real space; two-dimensional turbulence; energy transfers; enstrophy and kinetic helicity cascades; more complex applications, such as passive scalar, turbulent thermal convection, and magnetohydrodynamic turbulence.
Oct 10, 2018 · Turbulence is all around us, yet it's usually invisible. Simply wave your hand in front of your face, and you have created incalculably complex motions in the air, even if you can’t see it.
Jan 29, 2022 · Indeed, the reason for this complexity is a gradual development of very intricate, timedependent fluid patterns, called turbulence, rich with vortices - for example, see Figure 16. These vortices are especially pronounced in the region behind the moving body (the so-called wake), while the region before the body remains almost unperturbed.
