With release 1606 of OF there's a boundary condition for turbulent inlet which does not destroy the pressure field. It is supposed to be based on a Synthetic Eddy Method which is also Divergent Free and is implemented following this paper:
A New Divergence Free Synthetic Eddy Method for the Reproduction of Inlet Flow Conditions for LES
by Poletto, R., Craft, T., Revell, A.
http://link.springer.com/article/10....494-013-9488-2

But it seems this boundary condition is not easy to setup.
Since I couldn't manage to get any sensible numbers as input options I decided to go with a RAS run. After compiling the Lscale utility I made from R, then running this commands should prepare the input:

cd <boundaryLayer root>
blockMesh
simpleFoam
Lscale -latestTime
R -latestTime
sample -latestTime
mv postprocessing/surfaces/constantPlane/0.932 postprocessing/surfaces/constantPlane/0
cp -r postprocessing/surfaces/constantPlane/* ../boundaryLES/constant/boundaryData/inlet/
cd ../boundaryLES
blockMesh
pimpleFoam

assuming both cases are in the same directory, that should result in a turbulent boundary layer with reasonable pressure. However I'm not getting enough disturbances and the flow remains laminar with fluctuations. I tried playing around with k inlet condition of the RAS simulation but that did not affect the data. Am I miscalculating L?

I also tried using nCellsPerEddy 2; instead of the L file but that was of no help either.

I would appreciate any help on this matter.
