The model predicts combustor performance with a total temperature prediction accuracy of 0.5%.
Hydrogen addition improves combustion efficiency but increases CO emissions by 70% compared to propane.
This thermofluid network model operates 420 times faster than conventional CFD methods for system-level simulations.
Predictions of major species mass fractions for CO2 and H2O align well, although pollutant levels were notably miscalibrated.
