brock_bird_scaling

openpnm.models.phases.surface_tension.brock_bird_scaling(target, sigma_o, To, temperature='pore.temperature', critical_temperature='pore.critical_temperature')[source]

Uses Brock_Bird model to adjust surface tension from it’s value at a given reference temperature to temperature of interest

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.

  • To (float) – Reference temperature (K)

  • sigma_o (float) – Surface tension at reference temperature (N/m)

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

  • critical_temperature (string) – The dictionary key containing the critical temperature values (K)

Returns

value – A numpy ndarray containing surface tension values scaled to the temperature [N/m]

Return type

ndarray
