tyn_calus#

tyn_calus(target, VA, VB, sigma_A, sigma_B, temperature='pore.temperature', viscosity='pore.viscosity')[source]#

Uses Tyn-Calus model to estimate diffusion coefficient in a dilute liquid solution of A in B from first principles at conditions 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.

  • VA (float) – Molar volume of component A at boiling temperature (m3/mol)

  • VB (float) – Molar volume of component B at boiling temperature (m3/mol)

  • sigmaA (float) – Surface tension of component A at boiling temperature (N/m)

  • sigmaB (float) – Surface tension of component B at boiling temperature (N/m)

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

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

Returns

diffusivities – A numpy ndarray containing diffusion coefficient values [m2/s].

Return type

ndarray
