Default Permeability for porous zones

Hello, I have porous zones in my model, and I need help determining the permeability alpha and inertial coefficient C2, mentioned in the Fluent help. I know the porosity, and the actual geomtry of the perforated plates. However, I do not have pressure drop data. There is another equation that involves a C coefficient based on Reynolds number. In the help it says it is tabulated, but I do not know where to get the table values. Does anyone know where to find this table? Or does anyone know a different method for calculating permeability based on the geometry of the porous zone?

You need a function for the pressure drop through a perforated plate. Idel'Chik gives several such functions. Then you can set your function equal to the sink term from the FLUENT manual to solve for alpha and C2.
