PorousFlow Aqueous PreDis Mineral

This Material forms a std::vector of mineral concentrations (volume-of-mineral/volume-of-material) appropriate to the aqueous precipitation-dissolution system provided.

This computes mineral concentrations that result from a precipitation-dissolution (PreDis) kinetic reaction system. The Material Property may be saved in an AuxVariable using the PorousFlowPropertyAux AuxKernel. The mineral concentration computed has units m(precipitate)/m(porous material).

warning

The numerical implementation of the chemical-reactions part of PorousFlow is quite simplistic, with very few guards against strange numerical behavior that might arise during the non-linear iterative process that MOOSE uses to find the solution. Therefore, care must be taken to define your chemical reactions so that the primary species concentrations remain small, but nonzero, and that mineralisation doesn't cause porosity to become negative or exceed unity.

The computation uses a lagged approach for porosity to calculate the mineral concentration, : (1) where is the reaction rate (dependent on primary concentrations, etc) and is the saturation of the aqueous phase. Notice the use of the old value for porosity. This is an approximation. It breaks the cyclic dependency between mineral concentration and porosity: see Porosity for more details.
