mixture fraction of coal oxy-combustion (fuel: coal +CO2; oxidizer O2+CO2)

      co-axial flow arrangement: Coal + CO2 and aO2+bCO2
      DPM, species transport, 2-step reaction mechanism

      in the postprocessing, I used the local equivalent ratio to indicate the flame location, which  coincides with the flame.

      the issue is that it doesn't consider the diluted gas's impact: CO2 could be involved in the reaction.

      I used bilger definition, as shown below. the issue here is I don't know the volatile:CO2 ratio at the location I interested.

      Non-premixed model seems be able to do this job. but I use species transport model, not providing this option.
