Standard Roughness

HiĦĦ

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?

This is the picture of fluent wall options
