- PorousFlowDictatorThe UserObject that holds the list of PorousFlow variable names
C++ Type:UserObjectName
Controllable:No
Description:The UserObject that holds the list of PorousFlow variable names
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).
warningwarning
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, : 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.

# The dissolution reaction

#
# a' = -(mineral / porosity)' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is positive for a < 0.25, ie dissolution for a(t=0) < 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
# = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity
#
# This test checks that (a + c / porosity) is time-independent, and that a follows the above solution
#
# Aside:
# The exponential curve is not followed exactly because moose actually solves
# (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
# which does not give an exponential exactly, except in the limit dt->0

# The precipitation reaction
#
# a <==> mineral
#
# produces "mineral". Using mineral_density = fluid_density, theta = 1 = eta, the DE is
#
# a' = -(mineral / porosity)' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is negative for a > 0.25, ie precipitation for a(t=0) > 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
# = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity
#
# This test checks that (a + c / porosity) is time-independent, and that a follows the above solution
#
# Aside:
# The exponential curve is not followed exactly because moose actually solves
# (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
# which does not give an exponential exactly, except in the limit dt->0

# Example of reactive transport model with dissolution of dolomite
#
# The equilibrium system has 5 primary species (Variables) and
# 5 secondary species (PorousFlowMassFractionAqueousEquilibrium).
# Some of the equilibrium constants have been chosen rather arbitrarily.
#
# Equilibrium reactions
# H+ + HCO3- = CO2(aq)
# -H+ + HCO3- = CO32-
# HCO3- + Ca2+ = CaHCO3+
# HCO3- + Mg2+ = MgHCO3+
# HCO3- + Fe2+ = FeHCO3+
#
# The kinetic reaction that dissolves dolomite involves all 5 primary species.
#
# -2H+ + 2HCO3- + Ca2+ + 0.8Mg2+ + 0.2Fe2+ = CaMg0.8Fe0.2(CO3)2
#
# The initial concentration of precipitated dolomite is high, so it starts
# to dissolve immediately, increasing the concentrations of the primary species.
#
# Only single-phase, fully saturated physics is used.
# The pressure gradient is fixed, so that the Darcy velocity is 0.1m/s.
#
# Primary species are injected from the left side, and they flow to the right.
# Less dolomite dissolution therefore occurs on the left side (where
# the primary species have higher concentration).
#
# This test is more fully documented in tutorial_13

# PorousFlow analogy of chemical_reactions/test/tests/solid_kinetics/2species_without_action.i
#
# Simple equilibrium reaction example to illustrate the use of PorousFlowAqueousPreDisChemistry
#
# In this example, two primary species a and b diffuse towards each other from
# opposite ends of a porous medium, reacting when they meet to form a mineral
# precipitate. The kinetic reaction is
#
# a + b = mineral
#
# where a and b are the primary species (reactants), and mineral is the precipitate.
# At the time of writing, the results of this test differ from chemical_reactions because
# in PorousFlow the mineral_concentration is measured in m^3 (precipitate) / m^3 (porous_material)
# in chemical_reactions the mineral_concentration is measured in m^3 (precipitate) / m^3 (fluid)
# ie, PorousFlow_mineral_concentration = porosity * chemical_reactions_mineral_concentration

# The dissolution reaction, with limited initial mineral concentration

#
# a' = -(mineral / porosity)' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is positive for a < 0.25, ie dissolution for a(t=0) < 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
# = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity
#
# However, c(t=0) is small, so that the reaction only works until c=0, then a and c both remain fixed
#
# This test checks that (a + c / porosity) is time-independent, and that a follows the above solution, until c=0 and thereafter remains fixed.
#
# Aside:
# The exponential curve is not followed exactly because moose actually solves
# (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
# which does not give an exponential exactly, except in the limit dt->0
