OhmicConduction

class OhmicConduction(*args, **kwargs)[source]

Bases: openpnm.algorithms.ReactiveTransport.ReactiveTransport

A subclass of GenericLinearTransport to simulate electron and ionic conduction. The 2 main roles of this subclass are to set the default property names and to implement a method for calculating the effective conductivity of the network.

calc_effective_conductivity(inlets=None, outlets=None, domain_area=None, domain_length=None)[source]

This calculates the effective electrical conductivity.

Parameters
  • inlets (array_like) – The pores where the inlet voltage boundary conditions were applied. If not given an attempt is made to infer them from the algorithm.

  • outlets (array_like) – The pores where the outlet voltage boundary conditions were applied. If not given an attempt is made to infer them from the algorithm.

  • domain_area (scalar, optional) – The area of the inlet (and outlet) boundary faces. If not given then an attempt is made to estimate it, but it is usually underestimated.

  • domain_length (scalar, optional) – The length of the domain between the inlet and outlet boundary faces. If not given then an attempt is made to estimate it, but it is usually underestimated.

Notes

The area and length of the domain are found using the bounding box around the inlet and outlet pores which do not necessarily lie on the edge of the domain, resulting in underestimation of sizes.
