Prepared by Dr. Erno Sajo, Associate Professor, Department of Physics and Astronomy, Louisiana State University. Objectives. 3.1 Define the nature of the hazards associated with the air dispersion of hazardous chemicals. Uploaded on Feb … WebThere are two separate dispersion models in ALOHA: Gaussian and heavy gas. ALOHA uses the Gaussian model to predict how gases that have a buoyancy equivalent to air will disperse in the atmosphere. The heavy gas dispersion calculations that are used in ALOHA are based on those used in the DEGADIS model, one of several well-known …
