Application ID: 488
This non-conventional model of porous media flow utilizes creeping (Stokes) flow in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. The geometry used in the model was produced by scanning electron microscope images.
In this example, we take one of the 2D micromedia images of Keller, Auset, and Sirivithayapakorn and solve for velocities and pressures of pore fluids using the Stokes equations for Cartesian coordinates. Boundary integration is used to quantitatively evaluate fluxes.
This model example illustrates applications of this type that would nominally be built using the following products:Subsurface Flow Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the CFD Module, Chemical Reaction Engineering Module, Microfluidics Module, or Subsurface Flow Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
