TLDR
In this paper, the structure of soot was investigated within the fuel-lean (overfire) region of overventilated buoyant turbulent diffusion flames burning in still air, and the results showed that the structure varies with fuel type but is relatively independent of both position in the overfire region and flame residence time for the long residence time regime.About:

Light Scattering by Fractal Aggregates: A Review
TL;DR: In this article, the authors present a review of scattering and absorption of light by fractal aggregates, which are typically diffusion limited cluster aggregates with fractal dimensions of D.

Particle Morphology and Density Characterization by Combined Mobility and Aerodynamic Diameter Measurements. Part 1: Theory
TL;DR: In this article, a framework is presented for combining the information content of different equivalent diameter measurements into a single coherent mathematical description of the particles, which allows the placing of constraints on particle density, dynamic shape factor (x), and fraction of internal void space.
Journal ArticleDOI
Fractal and projected structure properties of soot aggregates
TL;DR: In this paper, the structure of soot aggregates was investigated, emphasizing the fractal properties as well as the relationships between the properties of actual and projected soot images. And the authors found that soot aggregate fractal property is relatively independent of fuel type and flame condition, yielding a fractal dimension of 1.82 with experimental uncertainties of 0.08 and 0.5, respectively.

Soot particle measurements in diffusion flames
TL;DR: In this paper, the formation and growth of soot particles in a coannular diffusion flame have been studied using a laser extinction/scattering technique for particle size measurement, and the results reveal that the flame can be broadly divided into two regions.
