Hello.

I am currently predicting some results for non premixed combustion by using methane or propane as fuel, and I am trying to show the contours for the Equivalence ratio. However, I have spent months trying to create a formula that I can set in the software (ANSYS CFX-Post) and then show the profiles post combustion, but i have not succeeded. I am working with a two steps reaction, by using CO, CO2, H2O,and NO as products. I have tried with the formula {1-((0.209-O2.Mass Fraction)/0.209) } however this does not show values richer than 1, and I dont know if its giving me sensible values.

I hope you can help me with this matter.

Many thanks on behalf.
