Estimating Permeability from Microscale Porous Structures

Application ID: 33331

This example shows how to estimate the permeability of a porous material by creating a detailed fluid flow model in a small unit cell. The result of the model is a lumped permeability of the material, which can be used in homogenized models using Darcy's law or the Brinkman equations. The permeability can be found under the Results->Derived Values node.

An even smaller unit cell could be used, 1/6 of the height of the current cell. This model has a few more cells added to it to make it more intuitive to visualize.

This model example illustrates applications of this type that would nominally be built using the following products:
