Modelling of air pollution

ΣΦΑΙΡΙΚΗ ΕΙΚΟΝΑ

Στόχοι

This activity aims to create a computer modelling of air pollution with chemical materials – gases or vapors with different origin – chimneys of production sites or reservoirs with chemical materials, fuels, etc.

Upon completion of this assignment the students will: • be aware of the nature of the atmospheric processes; • be able to work with ALOHA software for modelling air pollution; • be aware of the purpose of the software for modelling air pollution; • be able to implement technological solutions for accident prevention; • be able to estimate the magnitude of the polluted zone in case of pollution.

ALOHA is the hazard modeling software program for the CAMEO software suite, which is used widely to plan for and respond to chemical/hazardous materials emergencies. Details about a real or potential chemical/hazardous materials release can be entered into ALOHA and it will generate threat zone estimates for various types of hazards. ALOHA can model toxic gas clouds, flammable gas clouds, BLEVEs (Boiling Liquid Expanding Vapor Explosions), jet fires, pool fires and vapor cloud explosions. The threat zone estimates are shown on a grid in ALOHA and they can also be plotted on maps in MARPLOT, Esri's ArcMap, Google Earth and Google Maps. The red threat zone represents the worst hazard level; the orange and yellow threat zones represent areas of decreasing hazards.
