Introduction to Fire Dynamics Simulator and Smokeview

This 2 1/2 day course is intended for engineers with a strong background in fluid dynamics and fire dynamics. 

The Fire Dynamics Simulator is the newest and most versatile of the fire models developed by NIST.  The Fire Dynamics Simulator has been used for many types of problems like sprinkler activation in warehouse fires, tenability in residential fires, and smoke concentration in outdoor pool fires.

The NIST Fire Dynamics Simulator consists of two programs -  FDS and Smokeview. The NIST Fire Dynamics Simulator predicts smoke and/or air flow movement caused by fire, wind, ventilation systems etc. Smokeview visualizes the predictions generated by FDS.

FDS, a computational fluid dynamics (CFD) model, solves a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flows of smoke and hot gases generated in a fire.  FDS has integrated sub models that calculate many fire related phenomena such as radiative and convective heat transfer, sprinkler activation and sprinkler sprays, mixture fraction combustion model, and many others.
