### What is 'wavelength' with reference to turbuence?

Wavelength is with reference to Kolmogorov's theory of turbulence. Kolmogorov postulated a theory for how turbulence is conveyed from large to small scale eddies, as you described. The wavelength and ...

### Does turbulent river flow classify as uniform?

I'm not sure if there is any further context to this meme, but I would have chosen B) Unsteady Uniform Flow. Since almost all real flows are unsteady and non-uniform, it is really an application of ...

### Turbulence model for low reynolds problem

I solved my problem. I refined the mesh. Part of the problem was the high aspect ratio of my cells, because my tube is very thin in comparison to the length. I have solved the problem laminar and then ...

### Direction of rotation of turbulent eddies in channel flow

Non-laminar flow is often hard to characterize with much mathematical rigor (though in certain special cases and geometries may be done with a little limitation). The phenomena depends heavily on ...

### How safe is this assumption for turbulence modelling in porous media?

Short answer: The FLUENT approach is trivial. Many information are lost due to the space-averaging process - over a representative elementary volume - of the governing equations (which is the essence ...

### Ways to reduce turbulence in internal flows

Adding to these above ideas&techniques, In flexible pipes, along with the flexibility we can have filaments(flagellum ) on the walls. These could dissipate the turbulence kenetic energy for the ...

### Is inviscid flow necessarily turbulent?

The simple answer Reynolds number can be more simply defined as the ratio of Inertial forces to Viscous forces. viscous >> inertial = Laminar viscous << inertial = Turbulent This is why ...
