GeochemistryKineticRate
Defines a kinetic rate for a kinetic species. The general form of this rate is This is a rather complicated equation, and simple examples are given below. In this equation:
(units: mol.s) is the rate of the kinetic reaction. If it is positive then the kinetic species' mass will be decreasing (eg, dissolution). If it is negative then the kinetic species' mass will be increasing (eg, precipitation).
is the intrinsic rate constant. The product has units mol.s (assuming the simulation's time units are seconds). Note that mole units are used, even if the initial amount of the kinetic species is given in mass or volume units. Examples of are given below.
is either the surface area (units: m) for the kinetic species, or the specific surface area (units: m.g)
(units: g) is the mass of the kinetic species. It is optional. Examples are given below.

commentnote
Note that more than one GeochemistryKineticRate can be prescribed to a single kinetic species. The sum of all the individual rates defines the overall rate for each species (see Example 6). Simply supply your GeochemicalModelDefinition with a list of all the rates.
Example 1
Suppose that the kinetic rate is just a constant: for both the forward and backward reactions (ie, for precipitation and dissolution). Then set:
to the constant value, with units mol.s (assuming the simulation time is measured in seconds)
and
multiply_by_mass = falsedo not use any
promoting_species_namesorpromoting_species_indicesset and
set .
Example 2
Suppose that the kinetic rate for a certain mineral is proportional the mineral's surface area and that the surface area is known and fixed. Then set:
to the coefficient of proportionality, with units mol.m.s (assuming the simulation time is measured in seconds)
to the known mineral surface area, with units m
multiply_by_mass = falsedo not use any
promoting_species_namesorpromoting_species_indicesset and
set .
Example 3
Suppose that the kinetic rate for a certain mineral is proportional the mineral's free mass Then set
to the coefficient of proportionality, with units mol.g.s (assuming the simulation time is measured in seconds)
multiply_by_mass = true. MOOSE will automatically calculate the mineral's free mass depending on its molar mass and the number of free moles.do not use any
promoting_species_namesorpromoting_species_indicesset and
set .
Example 4
Suppose that the kinetic rate for a certain mineral is proportional the mineral surface area but that the surface area itself isn't known. Only the mineral's specific surface area (surface area per gram of free mineral m.g) is known. Then set
to the coefficient of proportionality, with units mol.m.s (assuming the simulation time is measured in seconds)
to be the mineral specific surface area, with units m.g.
multiply_by_mass = true. MOOSE will automatically calculate the mineral's free mass depending on its molar mass and the number of free moles.do not use any
promoting_species_namesorpromoting_species_indicesset and
set .
Example 5
Suppose that the kinetic rate for a certain redox couple is proportional the quantity of solvent water present: Then set
to the coefficient of proportionality, with units mol.kg.s (assuming the simulation time is measured in seconds)
and
multiply_by_mass = false.promoting_species_names = H2Oandpromoting_species_indices = 1set and
set .
Example 6
Suppose that the kinetic rate for a certain redox couple depends on the pH: For this, two GeochemistryKineticRate UserObjects must be created. Each has , multiply_by_mass = false, , and .
The first has ,
promoting_species_names = H+andpromoting_species_indices = 1.The second has ,
promoting_species_names = OH-andpromoting_species_indices = 1.5.
These are then supplied to the GeochemicalModelDefinition using its kinetic_rate_descriptions input.
Example 7
Suppose that the kinetic rate for a certain redox couple depends on the pH, the molality of Ca and the temperature: Then set
and
multiply_by_mass = falsepromoting_species_names = "H+ Ca++" and and promoting_species_indices = "1.5 0.3"

# Simulation to assess natural changes in the reservoir. Recall that water_60_to_220degC has provided a stable mineral assemblage that is in agreement with XRD observations, and a water at equilibrium with that assemblage. However, Stuart Simmons suggested including Laumontite and Zoisite into the simulation, and they were not included in water_60_to_220degC since they are more stable than Anorthite, so Anorthite completely dissolves when equilibrium is assumed. Here, all minerals suggested by Stuart Simmons are added to the system and kinetics are used to determine the time scales of the mineral changes. The initial water composition is the reservoir water from water_60_to_220degC.
# The initial mole numbers of the kinetic species are chosen to be such that:
# - the mass fractions are: Albite 0.44; Anorthite 0.05; K-feldspar 0.29; Quartz 0.18, Phlgoptite 0.02 and Illite 0.02 with trace amounts of the remaining minerals. These are similar to that measured in bulk X-ray diffraction results of 10 samples from well 58-32, assuming that "plagioclase feldspar" consists of Albite and Anorthite in the ratio 9:1, and that Biotite is Phlogoptite. The trace amounts of each mineral are necessary because of the way the kinetics works: precipitation rate is proportional to mineral-species mass, so without any mass, no precipitation is possible. Precisely:
# - it is assumed that water_60_to_220degC consists of 1 litre of water (there is 1kg of solvent water) and that the porosity is 0.01, so the amount of rock should be 99000cm^3
# - the cm^3 of the trace minerals Calcite and Anhydrite is exactly given by water_60_to_220degC (0.016 and 0.018 respectively)
# - see initial_kinetic_moles.xlsx for the remaining mole numbers
# The results depend on the kinetic rates used and these are recognised to be poorly constrained by experiment

# Simulates geochemistry in the aquifer. This input file may be run in standalone fashion but it does not do anything of interest. To simulate something interesting, run the porous_flow.i simulation which couples to this input file using MultiApps.
# This file receives pf_rate_H2O, pf_rate_Na, pf_rate_Cl, pf_rate_SiO2 and temperature as AuxVariables from porous_flow.i.
# The pf_rate quantities are kg/s changes of fluid-component mass at each node, but the geochemistry module expects rates-of-changes of moles at every node. Secondly, since this input file considers just 1 litre of aqueous solution at every node, the nodal_void_volume is used to convert pf_rate_* into rate_*_per_1l, which is measured in mol/s/1_litre_of_aqueous_solution.
# This file sends massfrac_Na, massfrac_Cl and massfrac_SiO2 to porous_flow.i. These are computed from the corresponding transported_* quantities.

# Simulates geochemistry in the aquifer. This input file may be run in standalone fashion, which will study the natural kinetically-controlled mineral changes in the same way as natural_reservoir.i. To simulate the FORGE injection scenario, run the porous_flow.i simulation which couples to this input file using MultiApps.
# This file receives pf_rate_H pf_rate_Na pf_rate_K pf_rate_Ca pf_rate_Mg pf_rate_SiO2 pf_rate_Al pf_rate_Cl pf_rate_SO4 pf_rate_HCO3 pf_rate_H2O and temperature as AuxVariables from porous_flow.i
# The pf_rate quantities are kg/s changes of fluid-component mass at each node, but the geochemistry module expects rates-of-changes of moles at every node. Secondly, since this input file considers just 1 litre of aqueous solution at every node, the nodal_void_volume is used to convert pf_rate_* into rate_*_per_1l, which is measured in mol/s/1_litre_of_aqueous_solution.
# This file sends massfrac_H massfrac_Na massfrac_K massfrac_Ca massfrac_Mg massfrac_SiO2 massfrac_Al massfrac_Cl massfrac_SO4 massfrac_HCO3 to porous_flow.i. These are computed from the corresponding transported_* quantities.
# The results depend on the kinetic rates used and these are recognised to be poorly constrained by experiment

# Simulation to check that the output of water_60_to_220degC is indeed at equilibrium with the mineral assemblage.
# The initial mole numbers of the kinetic species are unimportant for this simulation, but are chosen to be consistent with other input files. The numerical values are such that:
# - the mass fractions are: Albite 0.44; Anorthite 0.05; K-feldspar 0.29; Quartz 0.18, Phlgoptite 0.04 with trace amounts of Calcite and Anhydrite. These are similar to that measured in bulk X-ray diffraction results of 10 samples from well 58-32, assuming that "plagioclase feldspar" consists of Albite and Anorthite in the ratio 9:1, and that Biotite is Phlogoptite, and the 2% Illite is added to Phlogoptite. Precisely:
# - it is assumed that water_60_to_220degC consists of 1 litre of water (there is 1kg of solvent water) and that the porosity is 0.01, so the amount of rock should be 99000cm^3
# - the cm^3 of the trace minerals Calcite and Anhydrite is exactly given by water_60_to_220degC (0.016 and 0.018 respectively)
# - the total mineral volume is 99000cm^3, so that the porosity is 0.01
# - see initial_kinetic_moles.xlsx for the remaining mole numbers

# Simulation to assess possible changes in the reservoir. The rock composition from natural_reservoir.i is mixed with the water from water_3.i Note that the free_concentration values are used from water_3.i and that composition is held fixed throughout this entire simulation. This models water_3 continually flushing through the rock mineral assemblage: as soon as a mineral dissolves the aqueous components are swept away and replaced by a new batch of water_3; as soon as mineral precipitates more water_3 sweeps into the system providing a limitless source of aqueous components (in set ratios) at 70degC
# The results depend on the kinetic rates used and these are recognised to be poorly constrained by experiment
