Abstract

UV planar laser-induced fluorescence (PLIF) images of hot carbon dioxide (CO2) are obtained in a laminar flame (CH4/air) at high pressure (20 bar) with excitation wavelengths at 239.34 nm and 242.14 nm. Excitation wavelengths are chosen to minimize the contribution of nitric oxide and molecular oxygen LIF signals. Spectrally resolved single point measurements are used for correction of the remaining oxygen LIF interference. The continuum LIF signal from electronically excited CO2 is detected in a broad (280-400 nm) emission region. The UV PLIF of hot CO2 has the potential for application to a wide variety of diagnostic needs in high-pressure flames, combustors, and engines.
