- 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. [ 3 ][ 4 ]: 2 Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity.

Jul 28, 2023 · Turbulent flow or turbulence is a phenomenon that occurs when a fluid, such as water or air, moves irregularly and chaotically. It is characterized by the formation of eddies and vortices within the fluid.
5 days ago · Common examples of turbulent flow are blood flow in arteries, oil transport in pipelines, lava flow, atmosphere and ocean currents, the flow through pumps and turbines, and the flow in boat wakes and around aircraft-wing tips.

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.
Turbulence might be loosely defined as an irregular or random or statistical component of motion that under certain conditions becomes superimposed on the mean or overall motion of a fluid when that fluid flows past a solid surface or past an adjacent stream of the same fluid with different velocity.
Turbulence is axisymmetric if all the mean quantities are invariant under a rotation about one particular axis only (e.g. the z axis for stratified turbulence). Stationary, isotropic, homogeneous statistics are frequently assumed in theories of turbulence, but are in fact rare in geophysical contexts where stratification and Cori
Jan 1, 2015 · 1 Introduction. Similar to most flows of natural fluids, riverine flows are typically turbulent: turbulence is ubiquitous and represents a fundamental engine of transport, spreading and mixing. In particular, turbulence is the main sink of riverine flow total energy (E).
