Catalytic combustion of hydrogen

olegCFD · November 7, 2023, 06:12

I'm trying to simulate the catalytic combustion of a hydrogen/air mixture (5 % hydrogen and 95 % air) on platinum in 2d geometry.
The reaction mechanism includes only surface reactions and is imported in Chemkin format.
Also, computational domain consists of a gas region and a solid region (plate with platinum catalyst on interface).
Inlet and boundary temperature is 420 K.
The problem is that the reaction does not occur on the surface.

How to properly setup model?

my problem is like yours. did you solve it?

same problem here. did you able to find the solution?

I want to know about the procedure to solve heterogeneous reactions or in other words reactions on a particle surface, but I find zero solid phase particle in DPM post processing, Do you have any idea about this?
