Syntax

Intrinsic Permeability Scaling [{of} SpeciesName] = Kozeny ([Multiplier = multiplier] | [Phi_Ref = phi_ref])

Scope

Aria Material

Summary

Intrinsic Permeability scaling function using Kozeny’s model.

Description

Scales permeability by

S = M \frac{(1 - \phi_{ref})^2}{\phi_{ref}^3} \frac{\phi^3}{(1-\phi)^2}

If no value for \phi_{ref} is provided, the scaling is

S = M \frac{\phi^3}{(1-\phi)^2}
