Simulating the Fires in the World Trade Center

July 7, 2004
Author(s)
Kevin B. McGrattan, C P. Bouldin
The National Institute of Standards and Technology (NIST) is conducting a two year investigation of the World Trade Center disaster. Among numerous tasks, computer simulations of the fires are being conducted to provide structural engineers with a detailed

Fire Dynamics Simulator (Version 4) - User's Guide

July 1, 2004
Author(s)
Kevin B. McGrattan
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) modelof fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

Modeling Fire Growth and Spread in Houses. (Abstract/Presentation/Visuals)

December 1, 2003
Author(s)
Kevin B. McGrattan
In cooperation with the fire protection engineering community, a numerical fire model, Fire Dynamics Simulator (FDS), is being developed at NIST to study fire behavior and to evaluate the performance of fire protection systems in buildings. Version 1 of

Neighborhood-Scale Fire Spread

November 16, 2003
Author(s)
Ronald G. Rehm, D. D. Evans, William E. Mell, Simo A. Hostikka, Kevin B. McGrattan, Glenn P. Forney, Charles E. Bouldin, Elisa S. Baker
This paper describes development of a physics-based mathematical and computational model to predict fire spread among structures and natural fuels (trees, shrubs and ground litter). This tool will be used to understand how fires spread in a community where

Large-Scale Modeling of Fire Suppression with Water Sprays

September 2, 2003
Author(s)
Kevin B. McGrattan
The mechanisms underlying fire suppression by water can bedivided into gas and solid phase phenomena. Numerical models ofthese phenomena are dependent on the level of detail given to thecombustion and the fuel pyrolysis processes.Presently, models of gas

Unwanted Accelerated Burning After Suppressant Delivery

September 2, 2003
Author(s)
Anthony P. Hamins, Kevin B. McGrattan, Glenn P. Forney
In a number of real-scale fire tests, accelerated or enhanced unwanted burning has been observed immediately following the delivery of a fire suppressant. The conditions under which this phenomena occurs, its potential for harm, and its effect on the

Understanding Fire and Smoke Flow Through Modeling and Visualization

August 1, 2003
Author(s)
Glenn P. Forney, Daniel M. Madrzykowski, Kevin B. McGrattan, L M. Sheppard
Structural fires cost the American economy more than $100 billion annually in property damage, maintaining fire departments and insurance. A price cannot be put on the human toll: on average each year, 4,000 civilians die and 23,000 are injured in fires

Numerical Modeling of Pool Fires Using LES and Finite Volume Method for Radiation

June 16, 2003
Author(s)
Simo A. Hostikka, Kevin B. McGrattan, Anthony Hamins
The thermal environment in small and moderate-scale pool flames is studied by Large Eddy Simulation and the Finite Volume Method for radiative transport. The spectral dependence of the local absorption coefficient is represented using a simple wide band

ALOFT-PC: A Smoke Plume Trajectory Model for Personal Computers

March 1, 2003
Author(s)
William D. Walton, Kevin B. McGrattan, J V. Mullin
As the understanding of the capabilities and limitations of in situ burning of oil spills increases, in situ burning continues to gain acceptance as an oil spill mitigation tool. One widely imposed criteria for the use of in situ burning is limiting the
