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 storedpressure (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
