F071001 Transmission Electron Microscopy of Soot Particles in Diesel Spray Flame

Abstract

For better understanding of soot formation and oxidation processes in a diesel spray flame, morphology, size and nanostructure of soot particles in a diesel spray flame have been investigated using Transmission Electron Microscope (TEM). Recent invensigations by the authors include morphological variation along spray axis, fuel effects (conventional diesel, bio diesel, Fischer-Tropsch Diesel and aromatic additive effect), nanostucture analysis using High Resolution TEM (HRTEM), qualitative comparison among laser and TEM-based soot sizes, which all reflect and help better understanding of in-flame soot formation and oxidation processes.
