ordinary_diffusion#

ordinary_diffusion(phase, pore_diffusivity='pore.diffusivity', throat_diffusivity='throat.diffusivity', size_factors='throat.diffusive_size_factors')[source]#

Calculates the diffusive conductance of conduits in network.

Parameters:

  • phase (OpenPNM Phase object) – The phase object to which this model is associated (i.e. attached). This controls the length of the calculated array(s), and also provides access to other necessary properties.

  • pore_diffusivity (str) – Name of the dictionary key on the target object pointing to the array containing values of pore diffusivity

  • throat_diffusivity (str) – Name of the dictionary key on the target object pointing to the array containing values of throat diffusivity

  • size_factors (str) – Name of the dictionary key on the target object pointing to the array containing values of conduit diffusive size factors

Returns:

values – A numpy ndarray containing the computed values of diffusive conductance

Return type:

ndarray
