tial splitting operator. After each transport time step, the concentrations of
components within pore bodies and pore throats are transferred to BRNS for
calculation of chemical reactions. In the case of reactions with the solid surfaces,
pore geometries will change which, in turn, causes changes in porosity.
In such a cases, the pressure field will be recalculated after each reaction time
step to calculate new permeabilities. Through this process we can simulate
porosity/permeability evolutions due to chemical reactions, and calculate the
relation between permeability and porosity for a specific network [Raoof et al.,
2011].
