Simulation of microstructure/mechanism relationships in particle deposition

摘要: The important connection between particulate deposit properties and deposition mechanism remains poorly understood only scarcely studied. Accordingly, in this research, we develop a discrete stochastic model to simulate processes resulting from realistic combinations of mechanisms. Particle motion is assumed be determined by the superposition deterministic force that acts toward collecting surface random force, which produces Brownian diffusion. We characterize microstructure via porosity pore size/area distribution, area; examine evolution these descriptors with time (number particles deposited) for different also effect particle polydispersity, spatial orientation (for nonspherical particles), mean-free-path on structure.
