gaseous_species_in_water

openpnm.models.phases.partition_coefficient.gaseous_species_in_water(target, chemical_formula, temperature='throat.temperature')[source]

Calculate Henry’s law constant for gaseous species dissolved in water.

Parameters
  • target (OpenPNM Base object) – Object with which this model is associated. This controls the length of the calculated array, and also provides access to other necessary properties.

  • chemical_formula (string) – Chemical formula of the dissolving species.

  • temperature (str) – Name of the dictionary key on target where the array containing temperature values is stored

Returns

H – A numpy ndarray containing Henry’s law constant (Kpx) [atm/mol-frac]

Return type

ndarray
