Abstract:

This report presents the results of a study and experimental program undertaken to investigate the utilization of a laser Raman system in combustion research and engineering. The study discusses the possible instrument configurations that could be employed to produce an effective laboratory tool for combustion diagnostics. Test results are presented which show the operating characteristics of a modified pulsed nitrogen laser Raman system probing the exhaust of a T56 combustor rig operating under maximum power conditions. During the testing, N2, O2 and CO2 species were detected, the level of laser induced fluorescence background and its RMS fluctuation was determined and hot-band spectra of nitrogen suitable for use in temperature measurements was obtained.
