A simplified fuel-NOx model based on regression analysis

The mechanism of detailed chemical reactions in combustion is very complica ted, especially when the formation of a pollutant suck as NOx is considered . Based on regression analysis, a simplified fuel-NOx model is developed fo r premixed flame. The new model is available for a wider range of temeperat ure and fuel-air ratios compared with De Soete's (1975) fuel NO model. The reduction CHi species on NO is considered so that the model can be used in both fuel-lean and fuel-rich combustion systems. After a great simulation o f a one-dimensional premixed flame system using Miller and Bowman's (1989, Frog. Energy Combust. Sci., 15, 287) detailed elementary reaction model, th e calculation of all the reaction rates is presented based on regression an alysis. Copyright (C) 1999 John Wiley & Sons, Ltd.
