Abstract

Laser induced fluorescence (LIF) of carbon dioxide in high-pressure flames has been identified as a broad continuum (200-450 nm) with a faint superimposed structure. Signal variations correlate well with absorption cross-sections obtained from recent shock tube experiments. Linear dependence of CO 2 UV-LIF signal intensity versus pressure and laser fluence offers unique potential for imaging high-pressure flames. High-pressure flame (40-60 bar) imaging of carbon dioxide UV laser-induced fluorescence with 226 nm excitation is demonstrated in a CH 4/air flat flame.
