Hello,

I have some data simulating different types of ABL in a wind tunnel. The data are basically different velocities (u) at different height levels of the wind tunnel (y), with also known parameters to have the kinematic viscosity (v) and von Karman constant (κ).

I want to extract as many significant flow parameters as possible in order to draw conclusions about how certain profiles would fit in my velocity profiles given the specific circumstances of each flow flowing through my set-ups (with different roughness elements - hence roughness)

The question is how I can find some basic flow parameters like:

- displacement thickness δ*
- momentum thickness θ (would be useful to find also after the Reθ)
- boundary layer δ (not in all measurements the velocity u of the highest possible height is near u99 - so not obvious)


in order to use them afterward accordingly?

I know the formulas of the above parameters but I am not sure of how to find them based on my data.

Thanks in advance.
