spheres_and_cylinders

openpnm.models.geometry.conduit_lengths.spheres_and_cylinders(target, pore_diameter='pore.diameter', throat_diameter='throat.diameter')[source]

Calculates conduit lengths in the network assuming pores are spheres and throats are cylinders.

A conduit is defined as ( 1/2 pore - full throat - 1/2 pore ).

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_diameter (str) – Name of the dictionary key on target where the array containing pore diameter values is stored

  • throat_diameter (str) – Name of the dictionary key on target where the array containing pore diameter values is stored

Returns

lengths – Array (Nt by 3) containing conduit length values for each element of the pore-throat-pore conduits. The array is formatted as [pore1, throat, pore2].

Return type

ndarray
