Defining a Gas Mixture at Inlet Boundary
 

Hello everyone. I am trying to simulate a combustion chamber in ANSYS Fluent. The problem is that my inlet gas is composed of 15 different species and I am unable to find a solution for defining this mixture. Even in species transport, I can get maximum up to 7 species in a pre-defined model. Will be really thankful if someone can guide me in this regard ASAP please as the task is a bit orthent. Thanks in Advance.

Not sure why you are having trouble. Even on very old versions of Fluent I've run 50 species transport equations back when it was hard capped at 50 species. To my knowledge, the 50 species limit has been raised tremendously. It should not be the case that you are limited to 7 species.


Is your issue that Fluent just simply doesn't provide chemkin files specific to your case?

Thanks LuckyTran. The issue has been resolved
