Hi. I'm Kim. I have a problem.

I'm simulating scr catalyst reaction. So I used species transport wall surface reaction. And also shape of scr corrugated catalyst is so small compared to entire geometry, so I applied the porous media to replace catalyst.

Then after applying porous media, the chemical reaction only reacts to the surfase area[1/m] not with boundary conditions like temperature. And also product doesn't change according to arrhenius equation constant(A, Ea) but only surface area too.

My reaction fomula is

NH3 + V5+-OH > V-ONH4

Arrhenius equation constant

- A=8e+6, Ea=20000000, b=0

Can anyone tell me to apply porous media to wall surface reaction?
