摘要

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.
