JetA was chosen as an aviation fuel

while simplified flame front model

combustion chemical equilibrium model

combustion kinetic model

fuel atomization model

fuel evaporation model and emissions generation model were developed.The turbofan engine emissions (NOx

unburned hydrocarbons (UHC)

CO) under different operation conditions were calculated based on combustor multi-reactor model.The results show that

the higher combustion chamber flame temperature means the greater NOx emission levels;the fuel droplets atomization diameter is large when engine works under low rotate speed conditions

leading to increase of UHC and CO emissions levels;the combustor multi-reactor model has a better compatibility and fast computation speed

so it is considered as a promising method for integrating with engine performance program to predict the emission when the engine operates under different work conditions in design period of engine.
