Plume Mechanics and Particle Growth Processes.

Abstract

Numerical models have been developed for studying aerosol growth processes in dispersing smoke plumes. The principal growth processes are coagulation and condensation/evaporation. For coagulation, the existence of asymptotic limit distributions has been demonstrated. It is shown that the condensation/evaporation process can lead to multimodal particle size distributions. The aerosol growth processes have been incorporated in general K-theory model for dispersion of smoke plumes. Some of the results from field measurements of plumes from smoke munitions support conclusions based on our numerical model studies. (Author)
