7.6.9.7.1. Carmen_Kozeny

Syntax: Intrinsic Permeability [{of} SpeciesName] = Carmen_Kozeny (Sv = Sv | [Min_Porosity = min_porosity] | [Liquid_Phase_Name = Liquid_Phase_Name])
Scope: Aria Material
Summary: The Carmen-Kozeny model for permeability. $\kappa = \frac{1}{2 \tau^2 S_v^2}\frac{\phi^3}{(1-\phi)^2}$ , where $S_v$ is the surface-to-volume ratio. This form is from B.R. Corrochano et al. Journal of Food Engineering 150 (2015) 106-116 and reduces to the traditional form if $S_v = 6/d$ and $\tau = \sqrt(2.5)$ .
