Description
This course can be a module of the full 4 day Phast Advanced training or can be delivered standalone. This is a comprehensive course on the dispersion and toxic modelling available within Phast.

Topics covered include:

• The Unified Dispersion Model for outdoor releases
• Dispersion stages
• Ambient and terrain data
• Dispersion model components (jets, heavy-gas, passive dispersion)
• Thermodynamic model and rainout
• Finite-duration and time-dependent effects
• In-Building release model
• Building Wake Model for handling building wake effects
• Toxic effects models

For each topic, the course provides an overview of the basis of models, all the input variables, selection of suitable parameter values, and interpretation of the various reports and graphs. During the course, participants will be required to practise and apply their new knowledge of the software through extensive hands-on workshops.

Learning objectives
Upon completion of this course, participants will understand the theoretical and practical aspects of the Phast dispersion models. Participants will have a much more detailed knowledge of the discharge models available within Phast than those who have attended the SA-01 Phast introduction course only. They will have a much better understanding of the capabilities of the models, and their limitations, along with more detailed understanding of the controlling parameters.

Target group
People who need to carry out detailed consequence modelling calculations using Phast and need a good understanding of the theoretical basis of the dispersion calculations available within the software.
