The Coagulation and Dispersion of Nonspherical, Aerosol Particles in a Turbulent Atmosphere
Abstract
A numerical model was constructed for the simulation of dispersion and coagulation of a cloud of non spherical aerosol particles in turbulent conditions. Coagulation was observed in the early stages of the dispersion of the cloud. It appears from the calculations that, in a small cloud, dispersion is the dominant process from the early stages of the formation of cloud and coagulation stops after a short time. Nevertheless, at the time coagulation occurred it exhibited a behavior similar to what is expected from existing theories but modified by the strong dispersion of the cloud. The intention of the chief investigator, Prof. I. Gallily, was to perform numerical simulations with a much larger number of particles, to examine the behavior of the system with particles of different aspect ratios and to take account of the particle-particle hydrodynamic interaction. Due to the death of Prof. Gallily these additional goals were not achieved.
