Porous Reactor with Injection Needle
Application ID: 25
This model 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.
