Abstract : Soot formation in pyrolysis and combustion involves complex reaction systems with many species and individual reactions. It also involves the transition of a gaseous chemical system into a particle-containing (i.e., two-phase) system. Thus, there are various stages of the soot formation process on which to concentrate research investigations.

Formation of Hydrocarbons and Soot
1996Hydrocarbons and soot predate NO x (Chapter 17) as pollutants from combustion. In earlier times, smoke from the factory smokestack was a sign of prosperity. In time it became a nuisance and finally a health concern. The remedy to the appearance of soot and smoke are the three “t’s” of combustion: time, temperature, and turbulence (Babcock and Wilcox ...

Soot Formation in Unstrained Diffusion Flames
Combustion Science and Technology, 2014The formation of soot particles has been investigated in CH4/O2 diffusion flames using a unique burner design, which allows the creation of a nearly unstrained planar reaction sheet. Spatially resolved soot volume fractions were obtained using laser-induced incandescence.

Faraday Symposia of the Chemical Society, 1973
Probable mechanisms are discussed of the formation processes of pyrolytic carbon films and soot particles, based on experimental investigations of their formation rates. Both are two-stage processes including nucleation and growth of nuclei. The formation of pyrolytic carbon from methane at temperatures below 1300 K is a molecular process.

COULOMB INTERACTIONS IN SOOT PARTICLE FORMATION
Journal of Aerosol Science, 2001Soot formation from uncomplete combustion of hydrocarbons is important problem. However, there are many obscure areas in the mechanism of this process. For example, the role of Coulomb interactions in soot coagulation process is not clarified yet.

SOOT AND NANOPARTICLE FORMATION IN LAMINAR AND TURBULENT FLAMES
Combustion Science and Technology, 2007Abstract A new optical diagnostic method has been developed based on the interaction of a pulsed UV laser source with combustion-generated aerosols. This method allows characterization of nanoparticles of organic carbon (NOC) and soot by point measurements.

Model of Soot Formation: Coupling of Turbulence and Soot Chemistry
1994The aim of our study is to model soot formation in the extreme conditions of Diesel engines. The first concept has been to use a formulation for soot formation deduced from the most recent experimental work. However, in order to take into account the effects of turbulence and pressure, associated to soot production, we had to use very simplified ...

Polymer Degradation and Stability, 1990
Abstract Soot formed during the combustion of polymers is actually produced from the gas phase resulting from thermal decomposition of the polymer. The mechanisms of soot formation from gases are described. The description includes (i) the formation of soot precursors and soot particle inception, (ii) the aggregation of particles, (iii) the surface ...

Soot Formation in Vitiated Combustion
45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009This paper investigates the effect of vitiation on the soot formation process. The motivation behind this study is being able to define and predict the boundaries of flameless combustion as a function of soot precursor concentrations. Although the flameless combustion phenonmenon has varied applications, our primary interest is to predict the onset of ...

Soot From Fires: II. Mechanisms of Soot Formation
Journal of Fire Sciences, 1985The mechanisms described for soot formation have been reviewed. It is clear that no one simple mechanism can yet totally describe the complex processes in volved. It has been well established that ions have an important role in the nucleation stage, but controversy still surrounds the extent of their importance as precursors of soot.
