Q: How can I compare the eddy dissipation model rate with the chemical reaction rate in the ‘Finite Rate Chemistry and Eddy Dissipation’ turbulent combustion model in CFX?
A: For any reacting flow model, the overall rate is available in CEL and post-processing as ..Molar Reaction Rate. To output, in addition, the separate ..Eddy Dissipation Reaction Rate (i.e. the rate from the EDM) and the ..Chemical Reaction Rate (i.e. finite chemistry rate) you need to add the CCL to the Solver arguments:
-ccl short_rules.ccl
where short_rules.ccl contains:
LIBRARY:
VARIABLE: edmrate
Option = Definition
Output to Postprocessor = Yes
END
VARIABLE: kinrate
Option = Definition
Output to Postprocessor = Yes
END
END
