Combustion problem :confused:
 

Hello everyone,

I have a problem in combustion modelling. I have 4 burner in a combustion chamber. I want to simulate a failure in one burner. I changed the inlet to 'wall' and initialized the area above the burner. But after a few iterations fluent starts to create methane and a combustion in the burner. I have no idea where the methane comes from and it doesn't make any sense.

I use PDF Partially-Premixed-Combustion with ECFM, k-omega and non-transient...

Does anybody have a workaround or an idea for this problem?

Cheers
