Laser-Based Flowfield Imaging in a Lean Premixed Prevaporized Sector Combustor

By National Aeronautics and Space Administration

OH and fuel planar laser-induced fluorescence (PLIF) is used qualitatively in this study to observe the flame structure resultant from different fuel injector dome configurations within the 3-cup sector combustor test rig. The fluorescence images are compared with some computational fluid dynamics (CFD) results. Interferences in obtaining OH fluorescence signals due to the emission of other species are assessed. NO PLIF images are presented and compared to gas analysis results. The comparison shows that PLIF NO can be an excellent method for measuring NO in the flame. Additionally, we present flow visualization of the molecular species C2. Hicks, Yolanda R. and Locke, Randy J. and Anderson, Robert C.
