Hello, I'm trying to model a catalytic bed : the fluid enters the chamber and, on contact with the catalyst grains, decomposes into 2 gases. I use a porous region to model the catalyst grains.

I would like to simulate this decomposition using the reacting model with surface chemistry model but it is only available with multi-component liquid or multi-component gas and not multiphase. However I have a mix of liquid and gases... How can I proceed ?

Thank you
