How to model combustion with only methane stream?
 

I want to model combustion of a methane stream issuing into a quiescent closure(or space) filled wiht air.

Maybe non-premixed combustion in fluent can be used. But Fluent need at least a fuel stream and a oxdizer stream. In my case, fuel stream is methane. However, how to set the oxider stream? It is difficult to define oxdizer stream in fluent because oxdizer required for methane combustion is supplied by air in quiesecent closure.

It is a transient question.

How to deal with this case?

thanks

have you tried to set BC the mass fraction inlet for methane to 1 and then patch value in your quiescent closure for mass fraction to 0
