A combined experimental and detailed modeling study has been performed on a fuel-lean (qb = 0.64), 20-torr, low-pressure, burner-stabilized H2/N20/Ar flame. Species concentration and temperature profiles were obtained using molecular beam mass spectrometry and thin-wire Pt/Pt-Rh(10%) thermocouples,

✦ Synopsis
A recently developed research apparatus for characterization of low-pressure premixed flames has been developed and was used to characterize the C2H4/N2O/Ar flame at 20 torr. This instrument incorporates several diagnostic techniques in one apparatus so that individual techniques can be quantitatively compared and the usable detection range (both in terms of resolution and species detection) expanded. Results discussed in this report include mass analysis by triple quadrupole mass spectrometer and temperature measurement by thermocouple. Concentration profiles in the one-dimensional flame include CO, N2, and C2H4, at nominal m/z 28 as well as CO2 and N2O at m/z 44.
