Summary:On the base of the three-dimensional CFD simulation a simple reactor model to predict the pollutant formation in a combustor operating in a diffusion mode was built. This reactor model has been validated against NO x emission measured for model aero-engine combustor using both methane and kerosene as a fuel. It was shown that the predicted NO x emission index strongly depends on the applied reaction mechanism. The NO x emission indices calculated for methane-fueled and kerosene-fueled combustor using the developed reactor model and extended detailed reaction mechanisms for CH 4/air and C 10H 22/air mixtures are consistent well with the experimental data. The developed model was used to estimate the emission of different species involving sulfur compounds (SO 2 and SO 3), carbon oxide, and unburned hydrocarbons depending on power setting of gas-turbine aviation engine.
