poisson¶
- openpnm.models.physics.ionic_conductance.poisson(target, pore_permittivity='pore.permittivity', throat_permittivity='throat.permittivity', size_factors='throat.diffusive_size_factors')[source]¶
Calculate the ionic conductance of conduits in network (using the Poisson equation for charge conservation)
- 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.
pore_permittivity (str) – Name of the dictionary key on

pointing to the array containing values of pore permittivitythroat_permittivity (str) – Name of the dictionary key on
target
pointing to the array containing values of throat permittivitysize_factors (str) – Name of the dictionary key on
target
pointing to the array containing values of conduit size factors’
- Returns
values – A numpy ndarray containing the computed values of ionic conductance
- Return type
ndarray
