the hydrocarbonstate is stored in the reservoir state and
used instead of the primalvariable_
The initial hydrocarbonstate is computed using
initHydroCarbonState(...);
the results look okay, while the running for flow_solvent needs further
investigation even the results with flow_solvent actually look okay.
With two different version of
computePropertiesForWellConnectionPressures, flow_solvent produces the
same results. This is something needs further investigation.
The current implementation requires a copy of
computeWellConnectionPressure in StandardWells and StandardWellsSolvent.
That means probably we need to introduce the asImpl() for the Wells.
The solvent specify part of computeWellConnectionPressures is factored
out to computePropertiesForWellConnectionPressures in order to reuse
the computeWellConnectionPressures from the base model.
The following changes are done in order to remove the duplicated code in
assemble().
- extractWellPerfProperties takes SolutionState as input (only used in
the solvent model)
- the computation of effective parameters is moved to computeAccum()
With these changes the solvent model can use assemble() from the base
model.
The Todd-Longstaff model is extended to incorporate pressure effects
The solvent viscosity is then caculated as
mu_eff = mu_s^(1-\alpha * \omega) * mu_mix^(\alpha * \omega)
where \omega accounts for the porous media effects and \alpha =
\alpha(pressure) accounts for the miscibility of the solvent and oil
when contacted.
The \alpha values can be given using the TLPMIXPA keyword
If no entries are given to TLPMIXPA the table specified using PMISC will
be used as default.
IF TLPMIXPA does not appear in the grid \alpha = 1 and the pressure
effect is neglected.
This is tested in test_solventprops_ad.cpp
The most significant bug was in the computation of effective saturation
fraction for the gas phase. The current implementation differs from the
manual.
Add method to calculateEffectiveProperties (viscosity and density)
using the Todd and Longstaff model.
The effective properties are stored in mu_eff_ and b_eff_ in the
BlackoilSolventModel and accessed using fluidReciprocFVF and
fluidViscosity
The material balance scaling is extended to the solvent model
The gas value is used as default and an updateEquationsScaling() method
is added.
Minor modifications is done to the BlackoilModelBase.hpp and
BlackoilModelBase_impl.hpp in order to re-use code from the base case.
Solvent is accounted for in the calculations of well connection
pressures by adjusting the surface_density and the b-factor
