Calculation of gas recirculation ratio in MILD/flameless combustion?
 

Dear all,
Does anyone know how to calculate the gas recirculation ratio in the mild/flameless combustion mode as shown in the picture?

I am simulating the reacting flow in a combustion chamber in ANSYS FLUENT and I need to calculate its gas recirculation ratio for achieving such MILD or Flameless combustion regime.


My understanding, this gas recirculation ratiocan be calculated by using FLUENT CFD-post, but I don't know how to put that equation in CFD-post...
Have anyone guide me for this matter?
Thank you very much for helping...
