ADMS-Puff uses a Lagrangian puff methodology to model the fate of dense and passive gas releases. ADMS-Puff can use temporally and spatially varying meteorological data from the WRF model, or simple surface data. ADMS-Puff can also account for the impact of complex terrain: hills and variable surface roughness.
ADMS-Puff calculates snapshots of instantaneous air concentration along with a time integrated dose. These concentrations can be compared against regulatory or other levels, including inbuilt flammability limits.
ADMS-Puff has a link to Golden Software’s Surfer package for displaying contours of concentration overlaid on a map of the area where the incident occurred.
Operators and regulators concerned with determining the impact of dense gas releases.
ADMS-Puff has a user-friendly Windows interface, making it easy to set up the model and view results. The input data are arranged in a series of screens with default values provided for much of the information. This makes the model ideal for rapid data entry and use by non-specialists, e.g. in emergency situations.
The system has the following features:
