Raman investigation of a subsonic jet
A Raman apparatus for in situ analysis of the exhaust of a 1 kg/s mass flow rate combustor rig has been tested successfully. The concentrations of the dominant gases (N 2, O 2, CO 2, H 2 O) have been measured at 1100 K to within 5%. Below 1100 K, a strong fluorescence swamps the spectra. Tests condu...

| Summary: | A Raman apparatus for in situ analysis of the exhaust of a 1 kg/s mass flow rate combustor rig has been tested successfully. The concentrations of the dominant gases (N
2, O
2, CO
2, H
2 O) have been measured at 1100 K to within 5%. Below 1100 K, a strong fluorescence swamps the spectra. Tests conducted at 900 K demonstrate that this fluorescence can be used for a fast mapping of the jet density. |
