The ability to describe the complex pathways for the formation of NOx in combustion models is crucial because of the need to control NOx emissions. This project aims to overcome a limitation of present turbulent combustion based NOx models by using techniques for mechanism reduction to generate predictions based on detailed chemistry. A specific aspect of the programme, largely ignored in the past, is the inclusion of S-N interactions which have been shown experimentaly by the applicants and other workers to have a significant effect on practical low NOx turbulent diffusion flames. A full mechanism describing S-N chemistry will be developed using evaluated rate data, and a computationally efficient repro-model used to represent the full chemistry in CFD codes. The NOx model will be tested in (k- ...) and Reynolds-stress turbulent combustion codes with options for using either a 2-step global reaction model or a non-equilibrium strained flamelet model for comparison. Model predictions will be validated through a parallel programme of work, showing the effect of fuel S on thermal and fuel NOx formation using a 150 kW pilot-scale combustion facility.
