Hiˇˇ

How could I recreate standard roughness conditions over a 2D airfoil in fluent?
I am using this curves in order to validate my model and I don't know exactly if there is any way to set up standard roughness on my walls.

For what I read, standard roughness would be similar to tripping the boundary layer, but I don't know the exact value.

What I mean is this...

What values should I use in these options that fluent give me on wall boundary conditions in order to recreate the standard roughness of the wind tunnel data from NACA reports?
