water

openpnm.models.phases.thermal_conductivity.water(target, temperature='pore.temperature', salinity='pore.salinity')[source]

Calculates thermal conductivity of pure water or seawater at atmospheric pressure using the correlation given by Jamieson and Tudhope. Values at temperature higher the normal boiling temperature are calculated at the saturation pressure.

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.

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

  • salinity (string) – The dictionary key containing the salinity values. Salinity must be expressed in g of salt per kg of solution (ppt).

Returns

value – A numpy ndarray containing thermal conductivity of water/seawater in [W/m.K]

Return type

ndarray

Notes

T must be in K, and S in g of salt per kg of phase, or ppt (parts per thousand)

VALIDITY: 273 < T < 453 K; 0 < S < 160 g/kg; ACCURACY: 3 %
