sphere

openpnm.models.geometry.pore_surface_area.sphere(target, pore_diameter='pore.diameter', throat_cross_sectional_area='throat.cross_sectional_area')[source]

Calculates internal surface area of pore bodies assuming they are spheres, then subtracts the areas of the neighboring throats

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_cross_sectional_area (str) – Name of the dictionary key on target where the array containing throat cross sectional area values is stored

Returns

surface_areas – Numpy ndarry containing pore surface area values

Return type

ndarray

Notes

This function subtracts the area of the neighboring throats in a crude way, by simply considering the throat cross-sectional area, thus not accounting for the actual curvature of the intersection.
