Cluster-cluster aggregation with dipolar interactions

Accretional Remanence of Magnetized Dust in the Solar Nebula

“…(2)). This tendency toward lowering the fractal dimension has been studied before by Mors et al (1987), who performed numerical aggregation experiments with dipolar interaction. Helgesen et al (1988) verified computational predictions in two-dimensional aggregation experiments with magnetic microspheres.…”

A lattice chain model for the thermal restructuring of nanoparticle chain aggregates

“…Samson, Mulholland, and Gentry (1987) used an acetylene diffusion burner to produce soot aggregates with a fractal dimension of 1.5-1.6; Hurd and Flower (1988) report a fractal dimension of 1.49 for fumed silica aggregates; Zhang, Sorensen, Ramer, Olivier, and Merklin (1988) produced soot aerosol with a fractal dimension between 1.62 and 1.72 in a pre-mixed methane/oxygen flame. Long-range attractive interactions between colliding particles or aggregates may explain these small values (Mors, Botet, & Jullien, 1987;Hurd & Flower, 1988). Di Stasio (2001) reports the first direct observation of nanoparticle soot aggregate restructuring during their formation in an ethylene-air diffusion flame.…”

Eden growth model for aggregation of charged particles

“…However, inclusion of the long-range particle interactions, for example, of dipolar type, requires considerable CPU-resources. At present, such simulations are done only for the systems of moderate size [12]. However, this question is very important for the interpretation of the experimental data on magnetic particles aggregation [13].…”
