Study on NOx Formation in CH4/Air Jet Combustion

摘要: With the development of reaction kinetics and transfer science, modeling NO(subscript x) formation plays more important roles in protection environment design combustion reactors; this case, turbulence-chemistry model are two most aspects. For thermal mechanism, article studied CH4/air system applied a set latest NO rate constants published at Leed University which replaced original code FLUENT to increase its precision on prediction concentration. The realizable k-e model, Reynold Stress standard were also investigated predict turbulent reaction, indicated that simulation results velocities, temperatures concentrations productions by good accordance with experimental data. application data fit some kinetic parameters equation O atom revision later, obtained new model. It has been proved developed coincides well measurements.
