- Turbulence mixes heat, moisture, carbon dioxide and pollutants to and from the earth’s surface, maintaining our biosphere in a habitable state. Without turbulence, the air near the ground would be a lot hotter – when the sun is up, your feet would melt while your head would be freezing!

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...
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.
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.
Aug 24, 2017 · An improved understanding of turbulence and its implications for energy transfer could have big pay-offs for scientists — from astrophysicists who want to model how gas flows in galaxy clusters...

Dec 4, 2021 · Turbulence is typically described as a time varying phenomena of all dependent variables (except density for incompressible flows). In addition, spatial variations of the time dependency occurs as well.
Basics of Turbulent Flow. Whether a flow is laminar or turbulent depends of the relative importance of fluid friction (viscosity) and flow inertia. The ratio of inertial to viscous forces is the Reynolds number.
