The collapses of the World Trade Center towers on September 11, 2001, resulted from a combination of aircraft impact damage and the ensuing fires. This report documents: The information obtained on the factors that affected the nature, duration and

Improved Radiation and Combustion Routines for a Large Eddy Simulation Fire Model

June 16, 2005
Author(s)
Kevin B. McGrattan, J E. Floyd, Glenn P. Forney, Howard R. Baum, Simo A. Hostikka
Improvements have been made to the combustion and radiation routines of a large eddy simulation fire model maintained by the National Institute of Standards and Technology. The combustion is based on a single transport equation for the mixture fraction

Modeling Solid Sample Burning With FDS

June 1, 2005
Author(s)
Gregory T. Linteris, L W. Gewuerz, Kevin B. McGrattan, Glenn P. Forney
Black PMMA was burned in the cone calorimeter in two orientations (horizontal and vertical), at imposed radiant heat fluxes of (0, 5, 10, 25, 50, and 75) kW/m2, and the visual appearance, flame size, heat release rate, and mass loss rate were recorded

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

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
