How to set equivalence ratio in fluent
 

Hi.
I'm working on a project about mixing of air and hydrogen in a combustion chamber of a ramjet engine.

I want to have equivalence ratio of 1 for my case. But i have doubts about it.
How can i make it 1? I personally think i should make it by setting mole fractions in species tag in inlet boundary condition part. Is it right?

Thank you
