Air Dispersion Modelling

Atmospheric dispersion modeling

Is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms which simulate the pollutant dispersion. The dispersion models are used to estimate or to predict the downwind concentration of air pollutants or toxins emitted from sources such as building services processes e.g. boiler plant

Such models are important to Local Authorities and governmental agencies tasked with protecting and managing the ambient air quality and quite often a dispersion model is necessary for planning a biomass boiler installation. The modeling will determine if the stack height is sufficient to disperse the plume without adversely affecting the background air quality levels and are in compliance with the EU Ambient Air Quality Directive. The models also serve to assist in the design of effective control strategies to reduce emissions of harmful air pollutants.

The software used is based on the ADMS model which has been produced by Cambridge Environmental Research Consultants (CERC).
