comment Why is the turbulent energy cascade described as function of a wavenumber?
So exactly what non-linear waves are we talking about here?

comment Darcy law yields extreme speed for gas flow throgh packed spheres?
Additionaly, would using Forchheimer instead prinicpaly change the pressure diffreence magnitudes required to generate a given speed?

comment Darcy law yields extreme speed for gas flow throgh packed spheres?
Because I gave a hard time imagining 10 Pa pressure fluctuations cause a 10 cm/s speed in a packed bed. I am modelling combustion in porous media and it is very sensitive to velocity: $u=0.05$ m/s and $u=0.25$ m/s can yeild quite different results. And accoring to Darcy's law it seems that velocities would fluctate randomly in those value ranges because it is a matter of a few Pa fluctuations in pressure.

In that case, when is Darcy's law ever applicible for gas flow anyway? I mean, if even with a perssure difference of 10 Pa it is already unreasonable..

I think it does, it gives a reference too look up the BCs setup, fluent's theory guide is incredibly thorough.

comment Strict general mathematical definition of drag
I have all the flow characteristics as a solution in FLUENT. Integration can also be done numericaly. But,say, when I integrate he shear forces should I take only the components parallel to the flow direction at the inlet, or all of the components?

Flow is turbulent. I pretty much know everything about the flow in terms of a solution in FLUENT.
