A turbulent jet chemical reaction model: NOx production in jet flames

摘要

The Two-Stage Lagrangian turbulent jet reaction model is described, and results presented for NOx emissions from methane, CO-H-2, and hydrogen jet flames for a variety of conditions. The model includes complete chemical reaction mechanisms and treats the effects of buoyancy and radiation, the influences of which are shown to be significant. Non-equilibrium chemistry influences are also examined. The extensive comparisons made between the model and experimental results for the three fuels suggest that the model incorporates the essential processes that control NOx production in fuel jet flames.
