Turbulence - Wikipedia In fluid dynamics, turbulence or turbulent flow is fluid motion exhibiting 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]
Fluid Dynamics, Flow Patterns Turbulence - Britannica 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
Fluid mechanics - Turbulence, Flow, Dynamics | Britannica Turbulence arises not only in pipes but also within boundary layers around solid obstacles when the rate of shear within the boundary layer becomes large enough Curiously enough, the onset of turbulence in the boundary layer can reduce the drag force on obstacles
TURBULENCE Definition Meaning | Dictionary. com The word turbulence can be used to refer to atmospheric instability, such as sudden, unpredictable air movements resulting from a storm, but the word has a broader meaning as well and you will often hear it used to describe any situation characterized by unrest and disorder
What is flight turbulence and why does it happen? - BBC It can move the plane and cause sudden changes in height Most turbulence occurs in cloud where there are up- and downdrafts of wind, according to BBC Weather's Simon King, a former RAF officer
