Overview of HGSYSTEM
The links from the following table give a very brief sketch of what each module of HGSYSTEM can do.
|Data base of properties||DATAPROP|
|Near Field Dispersion||AEROPLUME||HEGABOX|
|Far Field Dispersion||HEGADAS||PGPLUME|
|Hydrogen Fluoride Models||HFSPILL||HFPLUME||HFFLASH|
Each of the HGSYSTEM modules can be run as a stand-alone model. However, the full benefit of the system is obtained by using a series of HGSYSTEM modules strung together to model a complete scenario ; composed of a source, near-field and far-field description of the dispersion process being studied.
For most modules of HGSYSTEM 3.0, two thermodynamical/chemical descriptions of the released pollutant are available to the user: full reactive chemistry and thermodynamics for an HF/water/inert ideal gas system or a new general non-reactive multi-compound two-phase aerosol model. The latter is new to version 3 and makes HGSYSTEM applicable to a very wide range of problems
