GASTAR - Dense Gas Dispersion Model
Entry ID: CERC_GASTAR
[ Get Service ]
[ Update this Record ]


Summary
Abstract: GASTAR is a dense gas dispersion model developed by CERC ideally suited to modelling accident and emergency response scenarios or investigating site safety involving releases of flammable and/or toxic materials from a variety of industrial accidents such as cryogenic spills, catastrophic tank failure, pipe fractures and multi-phase jets.

GASTAR is used for:

- risk assessment
- land-use planning
- emergency response planning
- management and training

GASTAR is an integral (or box) model. Using a combination of conservation laws applied to the cloud, supplemented by semi-empirical relations derived from dispersion research, it calculates spatially-averaged properties of the cloud, and their variation with distance downwind, and then applies profiles to give the concentration at any point. Novel features, such as slopes and obstacles, are incorporated into the integral formulation. Efficient solution algorithms require only seconds to solve a typical problem.

The application is simple to use, with a well-designed user-friendly Windows interface similar to other CERC models, simplifying input data entry and providing flexible examination of output. GASTAR is also supplied with a database of material properties for common toxic and flammable substances; further substances can be added by the user as required.
