I'm attempting to validate simulations of a swirling hydrogen-air mixture combustion, because I'm going to study the NOx formation and Its reduce in a fueled hydrogen combustion chamber. Only air have swirling effect. Hydrogen entering axial velocity inside CC. I known to constitute using combustion model (eddy break-up), turbulence model (RNG and/or RSM), radiation (P1 and DTRM model),define domain and Boundary condition in Fluent software. But I have not known following important cases and Therefore, I not to pass simulating stage.

Which NOx formation mechanism use Am I in my simulating? Besides,I have not reaction kinetic parameter(Ea, A,n;exponent of temperature) and reaction steps, In order to NOX formation reaction and hydrogen-air mixture combustion reaction

Above mentioned proplems to ask a favour of expert numerical combustion in fluent.

Yours Restpectfully. Ali

My proplem have same depression.

is there somebody for help? please, I would be very grateful.
