| Abstract | A new transmission electron microscopy (TEM) image processing method, the ROD method, is developed for deriving accurate parameters describing the morphology of soot aggregates generated in hydrocarbon air combustion systems. This new method was successfully demonstrated in the study of the morphology and fractal structure of a large population of soot aggregates thermophoretically sampled from the centerline of a co-flow ethylene/air laminar diffusion flame. The distribution of the primary particles within individual aggregate was studied using the ROD method based on their TEM images. The double-log-normal and a double-log-normal PDF provided the best fit to the measured data. Parameters describing the fractal structure of soot aggregates, fractal dimension = 1.77 and fractal prefactor = 2.48, were also obtained on ROD method. This is an abstract of a paper presented at the 30th International Symposium on Combustion. |
