fuller

openpnm.models.phases.diffusivity.fuller(target, MA, MB, vA, vB, temperature='pore.temperature', pressure='pore.pressure')[source]

Uses Fuller model to estimate diffusion coefficient for gases 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.

  • MA (float) – Molecular weight of component A [kg/mol]

  • MB (float) – Molecular weight of component B [kg/mol]

  • vA (float) – Sum of atomic diffusion volumes for component A

  • vB (float, array_like) – Sum of atomic diffusion volumes for component B

  • 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
