In this video, we showcase the Porous Reactor with Injection Needle model [http://www.comsol.com/model/porous-reactor-with-injection-needle-25] to help explain how you can use COMSOL Multiphysics to model chemical species reaction and transport in porous media.The transport properties, porous matrix properties, and reactions are all defined using theReacting Flow in Porous Media, Transport of Diluted Speciesinterface, which is found in the Chemical Reaction Engineering Module. The model then solves for the velocity and pressure of the flow, as well as the concentration of the reacting species. Finally, some adjustments are made to the model to increase the effectiveness of the reactor.More resources involving chemical reactors:
