- Abstract
- Soot clusters produced by partial oxidation of acetylene show three distinct phases--primary particles, agglomerates of the primary particles, and aggregates of the agglomerates. The dominant mode of soot formation can be controlled by the concentration of acetylene. Comparison of optical microscopy with inertial measurements indicate that the aggregates are not fractal but porous with a density of 0.094. Those simulations for the smallest aerodynamic diameter suggest a transition from aggregates which are fractal to agglomerates. Algorithms based on generalized Menger sponges are developed to simulate the transition from agglomerates to aggregates.
