Cover Story: A chemical reactor network model is proposed to simulate aeroengine burner emission and efficiency performance. In contrast to similar methods, its simplified partitioning into three subvolumes according to the axial distribution of the different air streams, paired with a proposed empirical tuning method, promotes the generality of the model without requiring engine-specific data. Its configuration produces a robust model capable of employing detailed kerosene combustion schemes to compute design-sensitive predictions of NOx, CO and unburnt hydrocarbons emissions. The model’s prediction trends are validated over actual engine tests and correlation methods, and it is integrated into open and closed design optimization loops to enhance the combustor’s performance. View this paper
