orthogonal permeability-resin infusion with FLUENT Software

Dear all
I want to analyze orthogonal resin infusion with FLUENT Software and I do not have permeability parameters for wide oblique shapes such as circular or oval shapes. Is it possible to use/expand experimental data (permeability parameters of Kx, Ky, Kz) obtained from a small flat surface? Please note that the permeability of a flat surface is fixed in all directions (x,y,z) but in a circular shape the parameters change according to the perpendicular curve coordinates. For example at the bottom of a circular curve, the thickness direction is parallel to Z axis (Z1) while at the sides it is perpendicular to the Z axis (Z2).
I really appreciate your help and effort for this research. Z2 Z1

The problem relies in the fact the your permeability parameters are align with the reinforced media fibers and in the mathematical model they are fixed according to the x, y and z axis. Are you using FLUENT? I have never solved anything like this and I'm not sure that you can do it with FLUENT. I know that you can change the permeability parameter orientation, however I think it is not possible to have them varying within the cells (volumes). In the window that you define the permeability parameter (in FLUENT) there is a button called "conical". It may be what you need, but I'm not sure.
