Research on Laser Scattering Property by Randomly Oriented Soot Clustered Agglomerates
Cluster-cluster aggregation (CCA) model based on Monte-Carlo method is used to simulate the structure of the fractal-like soot clustered agglomerates consisting of spherical primary particles,and numerical calculations are carried out on laser scattering by randomly oriented soot clustered agglomerates based on the discrete dipole approximation (DDA) method. Comparison of the laser scattering properties between equivalent spherical particles and randomly oriented soot clustered agglomerates shows that the differences between them are obvious. The scattering properties on randomly oriented soot clustered agglomerates are determined by the radius and number of primitive particles besides the refractive index. This research will provide an effective theoretical approach for the research of formation mechanism,structural characteristics of randomly oriented soot clustered agglomerates and propagation property of laser in them.
