Modelling and Simulation ofCO emission using Point Source Model

The framework for developing computerized software for air dispersion is presented in this
project. The software is called Plume Dispersion Modelling Software (PluDMS) which
focuses on carbon monoxide dispersion from a point source. PluDMS is developed using
Visual Basic (VB) programming language to specifically predict carbon monoxide
coiicentrations over distance. Atmospheric conditions and emission parameters are the
required inputs for the software. The output is the concentration of gas over the distance and
die fatahty predicted for that concentration dispersed. The software is vahdated using other
established air dispersion software; SCREEN3. Existing models are utilized to predict the
dispersion scenarios and their impact to the environment and humans. The model used in the
softwareis a Pasquill-GiffordGaussian point source model.
