P & I Design Ltd Chemical Engineers PC Toolkit DISPERSE The software is designed to predict the short term pollutant concentrations directly downwind (x direction) of an elevated point source at specified distances and as a function of atmospheric stalibility and wind speed. The model is based on the following assumptions:- Concentration profiles in the plume follow the Gaussian distribution in ...

DEVELOPMENT OF AN AIR DISPERSION MODEL FOR COASTAL ZONES AND COMPLEX TERRAINS Dr. D.Y.C. Leung Department of Mechanical Engineering HKU306/95E Introduction Various methods have been devised for the prediction of atmospheric pollution, which lead to over 100 types of model for different applications. The Gaussian air dispersion model, or its various segmented plume and puff advection progeny, is ...

Project Technical Documents DEGADIS: DESCRIPTION The DEGADIS model was originally developed for the U.S. Coast Guard and the Gas Research Institute primarily for simulation of the dispersion of cryogenic flammable gases. Subsequent work sponsored by the U.S. Environmental Protection Agency extended DEGADIS for simulation of the dispersion of vertical jets. Implementation of DEGADIS on a personal ...

Project Technical Documents SLAB: An Atmospheric Dispersion Model for Denser-Than-Air Releases DESCRIPTION SLAB is a computer model that simulates the atmospheric dispersion of denser-than-air releases. The types of releases treated by the model include a ground-level evaporating pool, an elevated horizontal jet, a stack or elevated vertical jet, and an instantaneous volume source. Except for ...
