Hello, I want to simulate NH3 combustion with GRI-Mech Mechanism from Reduced Mechanism by Hadi Nozari, H. Nozari and A. Karabeyoglu Fuel 2015 vol.159 223-233 DOI10.1016/j.fuel.2015.06.075

I used realizable k epsilon and EDC for the first model, and it converged. When I am trying realizable k epsilon with Eddy Dissipation, the solution is weird (20% oxygen at outlet, no NOx). How to solve it? Is it caused by the method that I used? Any tips about the method for combustion?

Thank you

(Note: I want to change to Eddy Dissipation because EDC needs longer computation time)
