Reduced Reaction Mechanisms for Ammonia Oxidation in Premixed Laminar Flames

摘要: Abstract Reduced reaction mechanisms are essential for the inclusion of direct kinetic effects into turbulent flame computations practical problems. In present paper reduced seven step, five step and four ammonia oxidation have been developed by study ofpremixed laminar flames. A systematic reduction technique using steady state assumptions intermediaries radicals has used to obtain schemes from a comprehensive detailed mechanism. Special emphasis given formation destruction NO N2O The tested comparing calculations performed with starting Results an extensive set flat premixed H2/O2 flames doped or nitric oxide diluted argon NH3/O2 presented. generally provide excellent agreement temperature, major species nitric-oxide profiles fo...
