Hello all!

I was wondering if anyone could point me on how to make a combustion model enriched with O2. I can successfully model a combustion of coal particles, but I cant specify a separate mass flow of O2, entering the chamber on a lance.

Thank you in advance

i also considering about this problem. do you use pdf modeling?

in the pdf modeling, the oxidiser can be defined as O2:21% and N2:79%. then you can define the O2 rich stream.

but I don't know how to define only one stream that O2 is enriched, but the others are ordinary stream.

any comments are appreciated.
