NIST has performed computer simulations of the fire using the newly developed, NIST Fire Dynamics Simulator (FDS) and Smokeview, a visualization tool, to provide insight on the fire development and thermal conditions that may have existed in the townhouse during the fire. Just launched this week by the International Society of Fire Service Instructors (ISFSI), “Safe Law Enforcement Operations on the Fireground” incorporates research from groups such as UL and the National Institute of Standards and Technology (NIST) to educate officers on the actions they should and shouldn’t take when they arrive before. NIST-FDS (NIST Fire Dynamics Simulator) is a computational fluid dynamics (CFD) model of fire driven fluid flow created by the US Building and Fire Research Laboratory which solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an emphasis on smoke and heat transport from fires.
