Spectroscopic studies of carbon monoxide: application for detection in flames
Résumé
In this study, we investigated both experimentally and numerically two-photon laser-induced fluorescence from
carbon monoxide (CO-TPLIF) in order to determine the applicability of this technique for imaging CO
concentration in aircraft combustion chamber. Experiments were carried out in an optical –accessible gas cell under
various conditions of temperature (300-900 K), pressure (0.1-3 MPa) and carrier gas (N2, air, He). Fluorescence
intensity decreases as temperature and pressure increase. Comparison between simulations and experimental results
show good agreement
