Hello Foam users,
I am simulating coal combustion in a rich fuel atmosphere, and the SurfaceReactionModel in Openfoam only has C (s)+O2=CO2. I need a multi-step surface reaction, and I have modified the COxidationKineticDiffusionLimitedRate, but warning has occurred. I don't know where the problem lies? Does anyone know where my mistake lies?
C (s)+O2=CO
C (s)+CO2=CO
C (s)+H2O=CO+H2

I solved it, it's just a matter of order.
There was no problem running the new surfacereactionmodel, but the result was incorrect. The combustion temperature was very low at only 1000k, and the CO+O2=CO2 in constant/reactions did not actually occur, which means there was no CO2 generation.

Did you manage to get a model running with acceptable results? I am busy with coal combustion and I am struggling. If you can help please.

Greetings.

Where exactly are you stuck?
