ExponentialLawPermeability¶

Source: models/porous_flow/ExponentialLawPermeability.py

Define the relationship between non-dimensionalized porosity and permeability.

The exponential porosity-permeability relation takes the form of \(K_0 \exp \left[ a(\varphi_o-\varphi) \right]\) where \(a\) is the scaling parameter; \(\varphi_0\) and \(K_0\) are the reference porosity and permeability respectively.
