Description
Summary:The generation of soot in combustion systems at temperatures between 1500-2500 K is studied. Soot formation is examined through the phases of particle inception and surface growth. Oxidation /pyrolysis of fuel molecules produces acetylene, its higher analogs, and polycyclic aromatic hydrocarbons. Surface growth comprises the attachment of gas phase particles to solid phase material; the amount of soot increases while the number of particles remains constant. The influences of laminar diffusion flames, fuel structure, pressure, additives, and oxidant composition are discussed. Soot formation in continuous spray combustion and diesel engines is described, and kinetic and liquid droplet models are explored and found to closely approximate a surface growth model.
