Flame temperature too low

Hello everyone.
I am currently trying to simulate a combustion of methane in a furnace with 4 inlets. Each inlet enters at a flow rate of 0.078 kg/s and the air and ch4 enter simultaniously. The mass fraction of ch4 is 0.33 and the mass fraction of o2 is 0.154 entering at 300K. I am getting the flame formed properly (I think) but the temperature is too low (800K) while I should be getting values close to 2000K. What might be wrong? I have tried to increase the temperature of the inlets but nothing changed. I am using a polynomial function for cp, thermal conducitivity and viscosity. Any help would be aprecciated. I have attached an image of a plane representing two of the inlets and the residuals. Thank you |

what combustion modelling approach did you used? EDC, EDM, Premixed, Non-Premixed? And also, which turbulence model did you adopted?
