Laser-Based Spectroscopic Studies of Propellant-Like Low-Pressure Flames

Abstract

A new generation of flat flame burner for characterization of one- dimensional premixed laminar flames has been developed to study the detailed flame chemistry relevant to gaseous flames of burning propellants. Experimental results provide temperature and species profiles which are necessary to validate flame models that are being developed to simulate propellant combustion. This facility is an integrated apparatus that presently consists of various laser- based diagnostic tools and thermocouples. This report discusses results obtained from C2H4/02/Ar and H2/NO2 low-pressure flames. Profiles for 0, H, OH, CH3, HCO, NO and N02 in the appropriate flames were obtained. Temperature profiles were taken of the flames and compared to temperatures obtained by OH laser-induced fluorescence. NO resonance-enhanced multiphoton ionization thermometry was tried and the results discussed. Comparison of C2H4/O2/Ar results are compared with modelling efforts.
