Modelling Passive Catalytic Recombiner (PAR)
 

Hello, everyone!
In my work I faced the problem of Passive catalytic Recombiner modeling.
Dear users of the software complex Star-ccm+ and just good people, tell me please, what model of physics to set? Share your thoughts and experience in this matter. I model recombinator hydrogen.
If you have questions about the input data or geometry, i will be happy to write.
Thanks your for you time!
