User talk:Student0531/Coherent turbulent structures
Notes
[edit]Provide more wikipedia links for terms such as, vorticity, mixing length model, Navier-Stokes equation, Reynold stress, Kelvin-Helmholtz instability, Lagrangian and Eulerian.
Introduction
[edit]- Consider simplifying the first sentence, maybe something like: Turbulent flows are complex multi-scale and chaotic motions that need to be classified into more elementary components.
- 'Time averages statistics can (instead of could) be applied'.
- 'but even these larger structures' seems unnecessary.
- Can you provide a reference for the first studies that started in the 1930s?
- 'and the dynamic properties govern' (instead of 'and then there are...that govern...').
- What does the fully developed approximation means?
History and Discovery
[edit]- Provide reference for Corrsin and Roshko data, and maybe also Hama's hydrogen bubble technique.
- The ability to compute [...] produces (instead of produced).
Definition
[edit]- Define all terms in the coherent vorticity formula.
- Some coherent structures, such as vortex rings, etc. can be large-scale motions comparable to...
Characteristics
[edit]- each coherent structure has its own...
- increase in volume due to (instead of caused by)?
- It is more believed that entrainment occurs... end of the sentence missing.
- The next most significant properties are...
- of such contours (not the such).
- the contours of coherent vorticity constitute (not constitutes).
- not only locate...but also identify (not identifies).
Formation
[edit]- Put the reference at the end of the sentence, not at the beginning.
- Coherent structures typically arise from the instability due to either ... (not either the instability due...)
- such rapid changes lead (not leads).
- structures [...] distort or interact (not distorts or interacts).
Categories of coherent structures
[edit]Lagrangian coherent structures
[edit]- I would use: 'groups of invariant sets that cause...'
Hairpin vortices
[edit]- from where the name originates.
- It is believed that production and contributions to Reynold stress, occur...
- Add reference about the 1991 definition of Robinson,s vortex structure.
