PorousFlow Aqueous PreDis Chemistry
This Material forms a std::vector of mineralisation reaction rates (L(precipitate)/L(solution)/s) appropriate to the aqueous precipitation-dissolution system provided. Note: the PorousFlowTemperature must be measured in Kelvin.
This computes reaction rates resulting from a precipitation-dissolution (PreDis
) kinetic reaction system.
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.
Details concerning precipitation-dissolution kinetic chemistry may be found in the chemical reactions
module. There are two main differences between the chemical reactions
module and PorousFlow
. These are:
The molar volumes must be specified in
PorousFlow
. This is so that the concentrations may be measured in rather than mol.m.Unlike the
chemical reactions
module, users ofPorousFlow
must specify the stoichiometric coefficients themselves. In each reaction, the primary concentrations (variables) must be brought to the left-hand-side. The right-hand-sides are the minerals, by definition. For instance, consider a 2-reaction system consisting of 3 primary variables, , and . The reactions areThen the
reactions
input is1 2 -3 4 -5 6
.
If the equilibrium constants are AuxVariables that depend on temperature (or other Variables) the computed Jacobian will not be exact and you may experience poor nonlinear convergence. If this becomes frustrating, please contact the MOOSE Discussion forum.

# 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

# 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 * saturation)
#
# This test checks that (a + c / (porosity * saturation)) 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

# 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
