Flame structure study of a lean H2/N2O/Ar Flame employing molecular beam mass spectrometry and modeling
A combined experimental and detailed modeling study has been performed on a fuel-lean (? = 0.64), 20-torr, low-pressure, burner-stabilized H2/N2O/Ar flame. Species concentration and temperature profiles were obtained using molecular beam mass spectrometry and thin-wire thermocouples, respectively. Species profiles include H2, N2O, N2, H2O, NO, O2, H, O, and OH. These profiles are compared with calculated profiles generated using PREMIX, a one-dimensional premixed laminar flame code. The detailed chemical mechanism employed in the code consists of 38 reactions and 14 species, and was derived from preliminary calculations using a more comprehensive set of reactions (> 200) obtained from a critical literature review. Rate and sensitivity analyses were performed on the PREMIX results using an interactive postprocessing code we have written so that the details of the chemistry may be understood. The results provide a stringent test of the detailed chemical flame model and chemical mechanism for the H2/N2O/Ar system.
