Atmospheric Dispersion Modeling of Reacting Chemicals

摘要

An advanced source characterization and dispersion modeling system for instantaneously released reacting chemicals has been developed. The model considers the complex interaction of three important components; physical, chemical, and thermodynamic. The physical component includes dense cloud slumping or buoyant puff rise, cloud lift-off and passive dispersion. The chemical component includes reaction with ambient air with an entrainment limited rate; and the thermodynamic component includes evaporation and condensation. The model also includes several databases containing physical, thermochemical and toxic data for a large number of species.
