tyn_calus_scaling

openpnm.models.phases.diffusivity.tyn_calus_scaling(target, DABo, To, mu_o, viscosity='pore.viscosity', temperature='pore.temperature')[source]

Uses Tyn-Calus model to adjust a diffusion coeffcient for liquids from reference conditions to 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.

  • DABo (float) – Diffusion coefficient at reference conditions

  • mu_o (float) – Viscosity at reference conditions

  • To (float) – Temperature at reference conditions

  • 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
