| Abstract |
The report gives results of experimental investigations aimed at developing nonperturbing, spatially precise, in-situ diagnostic techniques to measure species composition and temperature in flames. The investigations continued earlier development of coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced saturated fluorescence. The program included two main, concurrent tasks. In Task 1, optical thermometry, the practical feasibility of CARS was demonstrated in a program of research-scale combustor testing (results agreed to within 5% for combustion zone temperature measurements made with CARS and with shielded thermocouples). In Task 2, optical composition, laser-induced saturated fluorescence was examined in regard to its capability for measuring CH, CN, and NO concentrations in flames. Saturation of the fluorescence in CH and CN was achieved and considerable insight into the physics of saturated fluorescence was obtained. Promising initial results of NO fluorescence in flames are described, but saturation was not observed for laser spectral intensities up to 6 million W/sq cm/cm. |
