Turbulence is characterized by the following features: Irregularity Turbulent flows are always highly irregular. For this reason, turbulence problems are normally treated statistically rather than deterministically. Turbulent flow is chaotic. However, not all chaotic flows are turbulent. Diffusivity
Experts have described turbulence as ‘common’ and asserted that it ‘rarely’ leads to fatalities.
The propensity of a fluid to swirl is used to promote good fuel/air mixing in internal combustion engines.. In fluid mechanics and transport phenomena, an eddy is not a property of the fluid, but a violent swirling motion caused by the position and direction of turbulent flow.
That is the reason why down-gradient eddy diffusion models are often referred to as "Fickian", emphasizing this mathematical similarity. Note that the eddy diffusivity K {\textstyle K} can in general be a function of space and time, since its value is given by the pattern of eddies that can evolve in time and vary from place to place.
In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues such as clouds, ...
Here's what to know about why and how to stay safe. Climate change is making turbulence worse, but here's why you shouldn't worry (too much) Skip to main content
Turbulence is a difficult phenomenon to model and understand, and it adds another layer of complexity to the problem of solving the Navier–Stokes equations. To solve the Navier–Stokes equations, we need to find a velocity field v ( x , t ) {\displaystyle \mathbf {v} (x,t)} and a pressure field p ( x , t ) {\displaystyle p(x,t)} that satisfy ...
Turbulence or pockets of disturbed air can have many causes, most obviously the unstable weather patterns that trigger storms, according to an industry briefing by planemaker Airbus. The resulting ...
