- What is the mystery of turbulence? - Physics Stack Exchange
What is called turbulence are precisely those states where the flow is irregular However as this transition to turbulence depends on the constituents and parameters of the system and leads to very different states, there exists sofar no general physical theory of turbulence
- What are the length and time scales in turbulence?
I haven't been able to understand what are does someone mean by length and time scales, while talking about turbulence Can someone explain it?
- Why is turbulence dissipation $\epsilon$ defined this way?
This term is turbulence kinetic energy dissipation rate $\epsilon$, which represents the rate at which Kolmogorov eddies energy is converted back into the flow’s internal energy I understand the physic of energy cascade and turbulence dissipation, but I don't understand how did we relate the above definition to turbulence dissipation?
- Taylors hypothesis in turbulence - Physics Stack Exchange
The "Taylor Hypothesis" is founded on the idea that the changes observed in any given measured in the propagate at speeds much much less than the bulk flow speed of the solar wind (well, this has been applied in other regions of space than just the solar wind, but it's most commonly assumed there) We start with the nonrelativistic relation (i e , assume V c 1) given by: where is the observed
- What does “eddy” mean in turbulence? - Physics Stack Exchange
a newbie in turbulence study, very confused about the concept of eddy, I feel the word quot;eddy quot; having two meanings in fluid-mechanics maybe more and i'm not sure if i understand correctly

- Estimating Aircraft Turbulence Severity from Velocity and Acceleration
Define “turbulence” When I’m on a plane and they say “we’re gonna go through some turbulence”, I usually think of high-amplitude oscillations in acceleration on me as what’s coming next Is that what you mean?
- fluid dynamics - What is enstrophy? - Physics Stack Exchange
Note that the vortex stretching -> turbulence cascade connection in the enstrophy -> vortex stretching -> turbulence cascade is a jump I made, not the text Not sure how valid it is, iirc it's been shown that vortex stretching is not the only dominant term in the turbulence cascade
