Default turbulence generator @ Inlet for LES

canopus is on a distinguished road
I have mean velocity and turbulent kinetic energy profiles
from experimental data. I want to use this as an input to
my FORTRAN LES code.

Can you please suggest(hints/literature) what are the simple methods to generate a fluctuating field at inlet using the data above?

I have tried random fluctuations based on random number generator
but they do not seem satisfactory.

Best regards

hello every one.
i want to model a isotropic turbulent flow with openfoam.
my case is a turbulence generator in a wind tunnel.
i just know the velocity of air at entrance of the tunnel
i want to model it with simplefoam.
what boundary condition must i choose for P and U and ....?
please help me
