21.1.3 Postprocessing

When you compute NOx formation, the following additional variables will be available for postprocessing:

• Mass fraction of Pollutant no

• Mass fraction of Pollutant hcn (appropriate fuel NOx model only)

• Mass fraction of Pollutant nh3 (appropriate fuel NOx model only)

• Mass fraction of Pollutant n2o (N $_2$O-intermediate model only)

• Mass fraction of Pollutant urea (SNCR urea injection)

• Mass fraction of Pollutant hnco (SNCR urea injection)

• Mass fraction of Pollutant nco (SNCR urea injection)

• Mole fraction of Pollutant no

• Mole fraction of Pollutant hcn (appropriate fuel NOx model only)

• Mole fraction of Pollutant nh3 (appropriate fuel NOx model only)

• Mole fraction of Pollutant n2o (N $_2$O-intermediate model only)

• Mole fraction of Pollutant urea (SNCR urea injection)

• Mole fraction of Pollutant hnco (SNCR urea injection)

• Mole fraction of Pollutant nco (SNCR urea injection)

• no Density

• hcn Density (appropriate fuel NOx model only)

• nh3 Density (appropriate fuel NOx model only)

• n2o Density (N $_2$O-intermediate model only)

• urea Density (SNCR urea injection)

• hnco Density (SNCR urea injection)

• nco Density (SNCR urea injection)

• Rate of no (from the individual pathways)

• Rate of hcn (appropriate fuel NOx model only)

• Rate of nh3 (appropriate fuel NOx model only)

• Rate of n2o (N $_2$O-intermediate model only)

• Rate of urea (SNCR urea injection)

• Rate of hnco (SNCR urea injection)

• Rate of nco (SNCR urea injection)

These variables are contained in the NOx... category of the variable selection drop-down list that appears in postprocessing dialog boxes. Additional NO rates from individual pathways, Thermal, Prompt, Fuel, N2O Path, and SNCR can be plotted.
