Morphology and structure of soot emitted from various aircraft engines
Résumé
We present here an experimental characterization of the morphology, structure and chemical properties of soot particles emitted from various aircraft engines (CFM56-5C, -7B, SaM-146), and a combustor [Delhaye, 2008 ; Petzold, 2011]. Soot particles have been collected by direct impaction on electron microscope grids. Transmission electron microscopy (TEM) is used to determine the aggregates fractal dimension as well as soot primary particles and aggregates size distributions. The morphology, structure and texture of primary particles are also determined in addition to the elemental composition by the mean of X-ray energy dispersive spectrometry (XREDS).
