Non premixed combustion
 

Hi, I am modeling Counterflow Diffusion Flame (with the inlet velocities of fuel and oxidizer to be same) using non-premixed combustion model with equilibrium chemistry . The simulation is going well, but the flame profile is more like the premixed combustion and the combustion is not taking place at the stagnation plane. Can anyone please tell me where am I going wrong. Thanks in advance.

Shams.
