Free Convection in a Porous Medium
Application ID: 278
This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field.
The model couples the momentum balance to an energy balance through an equation, dependent on temperature, being directly typed into the source term for the momentum balance. This shows COMSOL Multiphysics' unique equation-based modeling abilities and can be considered as a benchmark model for COMSOL Multiphysics capabilities in single-phase porous media flow.
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
- Batteries & Fuel Cells Module, CFD Module, Chemical Reaction Engineering Module, Microfluidics Module, or Subsurface Flow Module and
- Batteries & Fuel Cells Module, CFD Module, Chemical Reaction Engineering Module, Corrosion Module, Electrochemistry Module, Electrodeposition Module, Heat Transfer 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.
