What's New in Version 2.0
  • Updated numerous Source Term Wizard calculations to use more modern and powerful methods
  • Enhanced the Chemical Database by adding new chemical properties in the Pool Evaporation Tab
  • Added a new Chart Tab that allows users to view the time series Source Term Wizard results and dispersion concentration results in a table or chart format
  • Enhanced the SLAB model to allow the user to specify the time step used for calculating and displaying at discrete receptors
  • Updated the Richardson Number calculation method to incorporate more commonly used equations
Program Characteristics
  • Incorporates established, proven models developed by the U.S. EPA, U.S. military and Coast Guard, and industry groups
  • Utilize well-documented, widely-accepted models: understand what your model is doing rather than trusting proprietary “black box” models
  • Achieve trustworthy results for a fraction of the cost and time of CFD systems
  • Reduce or eliminate the need to hunt for chemical properties with built-in chemical database
  • Shorten model setup and execution time with intuitive ribbon bar interface and scenario templates
  • Includes BREEZE 3D Analyst for visualization of results, export to Google Earth, etc.
  • Improved Chemical Database, including the ability to edit the database without having administrator privileges
  • Added a Table Objects Tab to speed up scenario setup and editing of sources
  • Updated ComponentOne to the latest version to improve stability and pave the way for additional improvements in the future
Toxic/Flammable Gas Dispersion Models
  • Model dense gas plumes and evaporating chemical pools with DEGADIS and SLAB
  • Model neutrally-buoyant gas plumes, including moving sources, with AFTOX and INPUFF
  • Simplify computation of release characteristics (e.g. exit velocity and temperature) when they are not explicitly known with the Source Term Wizard
  • Translate results from raw concentrations to designation of safe and hazardous areas quickly with Level of Concern database (e.g. IDLH and PEL for toxic gases, LEL or LFL for flammable gases)
Fire (Thermal Radiation) and Explosion (Overpressure) Models
  • Predict thermal radiation exposure and temperature rise with the unconfined pool fire, confined pool fire, vertical jet fire (flare), and BLEVE models
  • Model vapor cloud explosions with Baker-Strehlow-Tang, TNO Multi-Energy, U.S. Army TNT Equivalency, and U.K. HSE TNT Equivalency models
