Returns the mol (!) fraction of CO2 in the liquid phase and the mol_ (!) fraction of H2O in the gas phase for a given temperature, pressure, CO2 density and brine salinity.
Implemented according to "Spycher and Pruess 2005" applying the activity coefficient expression of "Duan and Sun 2003" and the correlations for pure water given in "Spycher, Pruess and Ennis-King 2003"
Parameters
temperature the temperature [K]
pg the gas phase pressure [Pa]
salinity the salinity [kg NaCl / kg solution]
knownPhaseIdx indicates which phases are present
xlCO2 mole fraction of CO2 in brine [mol/mol]
ygH2O mole fraction of water in the gas phase [mol/mol]
