Anisotropic Hygroscopic Porous Medium
Application ID: 113941
This example compares moisture transport within two types of anisotropic porous medium. The first component defines a layered structure. The structure alternates between layers with high and low moisture diffusivity. So the moisture spreads more easily along the layers than transversely. The second component has a single domain with an effective, anisotropic moisture diffusivity. The relative humidity distribution for the two cases are then compared.
This model example illustrates applications of this type that would nominally be built using the following products:
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 Heat Transfer Module, or Porous Media 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.
