Abstract

For better understanding of soot formation and oxidation processes in diesel spray flame, multi-point synchronous thermophoretic soot sampling was taken to obtain more information about soot morphology and size distribution in diesel spray flame. Soot samples were collected by thermophoretic sampling method in a constant volume combustion chamber. 9 different fixed sampling points were adopted for soot sampling and transmission electron microscope observation. Soot morphology and size distribution regularity in cone-shaped diesel spray flame were concluded with combustion status diagnoses. Detailed soot distribution and evolution regularity in both spray centerline horizontal direction and radial direction were gained by experimental results. Soot correlation reaction ratio in different region and combustion stage, reaction affecting factors were deeply discussed.
