Porous Reactor with Injection Needle

Application ID: 25

This application treats the flow field and species distribution in an experimental reactor for studies of heterogeneous catalysis. The model exemplifies the coupling of free and porous media flow in fixed bed reactors.

The reactor consists of a tubular structure with an injection tube that has its main axis perpendicular to the axis of the reactor. The incoming species in the main and injection tubes reacts in a fixed porous catalyst bed. The model couples the free fluid and porous media flow through the Navier-Stokes equations and Brinkman’s extension of Darcy’s law. The mass transport for the three species is modeled with the convection-diffusion equation.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
