Porous Reactor with Injection Needle
Application ID: 25
Modeling packed beds, monolithic reactors, and other catalytic heterogeneous reactors is substantially simplified with the Reacting Flow in Porous Media multiphysics interface. This defines the diffusion, convection, migration, and reaction of chemical species for porous media flow without having to set up separate interfaces and couple them. The multiphysics interface automatically combines all of the couplings and physics interfaces required for the modeling of heterogeneous catalysis together with porous media flow and dilute or concentrated chemical species transport.
As this multiphysics interface complements similar ones for laminar and turbulent flow, you can switch or define new couplings to other types of flow models without having to redefine and set up a new interface for the participating physical phenomena. The Settings window allows you to select the type of flow to be modeled as well as the transport of chemical species without losing any of the defined material properties or reaction kinetics. This means that you can compare different reactor structures or model flow in both free and porous media in one reactor, even when the two regimes are connected.
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 CFD Module, Chemical Reaction Engineering Module, Corrosion Module, Electrochemistry Module, Electrodeposition Module, Microfluidics Module, Porous Media Flow 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.
