Permeability of porous media
 

Since FLUENT porous characteristics are based on 100% open media, if:

permeability=K, porosity=phi

which of the following relations should be applied in fluent porous dialog box for viscous resistance according to 100% open media:

1. (1/K)

2. (1/K) Ã- phi

3. (1/K) / phi
