- water_correlation(phase, T='pore.temperature', salinity='pore.salinity')[source]#
Calculates thermal conductivity of pure water or seawater at atmospheric pressure using the correlation given .
Values at temperature higher the normal boiling temperature are calculated at the saturation pressure.
phase (OpenPNM Phase object) – The phase object to which this model is associated (i.e. attached). This controls the length of the calculated array(s), and also provides access to other necessary properties.
T (str (dict key) or numeric) – Name of the dictionary key on
phasecontaining the ndarray of temperature values, in units of [K]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.
salinity (str) – The dictionary key containing the salinity values in g/kg
value – A numpy ndarray containing thermal conductivity of water/seawater in [W/m.K]
- Return type:
T must be in K, and S in g of salt per kg of phase, or ppt (parts per thousand). The correlation is valid for 273 < T < 453 K and 0 < S < 160 g/kg within 3 percent accuracy.
