In Situ Burning of Oil Spills: Mesoscale Experiments and Analysis (NIST SP 995)

March 1, 2003
Author(s)
William D. Walton, D. D. Evans, Kevin B. McGrattan, Howard R. Baum, W H. Twilley, Daniel M. Madrzykowski, Anthony D. Putorti Jr., Ronald G. Rehm, H Koseki, E J. Tennyson
A series of six mesoscale and one large laboratory fire experiments were performed to measure the burning characteristics of Louisiana crude oil on water in a pan. These included one - 6 m square and five - 15 m square mesoscale burns and one - 1.2 m

Improvements to the NIST Fire Dynamics Simulator

January 1, 2003
Author(s)
Kevin B. McGrattan, J E. Floyd, Glenn P. Forney, Howard R. Baum, Simo A. Hostikka
A new version of the NIST Fire Dynamics Simulator (FDS) was released in the fall of 2001. Improvements have been made to the combustion and radiation routines, allowing for better simulation of flashover. The combustion is based on a single transport

Future of Fire Simulation

December 1, 2002
Author(s)
Kevin B. McGrattan, Howard R. Baum, Ronald G. Rehm, Glenn P. Forney, Kuldeep R. Prasad
Scientists and engineers are often asked to make predictions of the state of technology in the future and are usually laughably wrong. The best prognosticators get the trends right, but cannot possibly fill in the details. Think of Jules Verne predicting a

Fire Dynamics Simulator (Version 3): Users Guide (NISTIR 6748)

November 1, 2002
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka, Kuldeep R. Prasad
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of 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

Enclosure Effects on Flame Spread Over Solid Fuels in Microgravity

September 1, 2002
Author(s)
Y N. Nakamura, Takashi Kashiwagi, Kevin B. McGrattan
Enclosure effects on the transition from localized ignition to subsequent flame spread over a thermally-thin solid fuel in microgravity are investigated numerically solving the low Mach number time-dependent Navier-Stokes equations. The numerical model

Large Eddy Simulation of Buoyant Turbulent Pool Fires

July 25, 2002
Author(s)
J Gore, Kevin B. McGrattan, Ronald G. Rehm, Howard R. Baum
Three dimensional large eddy simulations (LES) of two buoyant flows were performed n conjunction with a Smagorinsky turbulence model. The flows included a non-reacting helium plume previously simulated with two-dimensional simulations and a methane/air

Community-Scale Fire Spread

July 1, 2002
Author(s)
Ronald G. Rehm, Anthony P. Hamins, Howard R. Baum, Kevin B. McGrattan, D D. Evans
This paper addresses community-scale fires, which have also been called urban/wildland interface or intermix fires. These fires arise when wildlandfires invade the built environment and attack structures as well as wildland fuels. The prediction of the

Initial Model for Fires in the World Trade Center Towers

May 1, 2002
Author(s)
Ronald G. Rehm, William M. Pitts, D D. Evans, Kuldeep R. Prasad, Kevin B. McGrattan, Glenn P. Forney
Mathematical models have been used to provide an initial estimate the behavior of the fires in the twin towers of the World Trade Center (WTC) on September 11, 2001. Available photographs and videos have provided an initial estimate of the exterior damage

Initial Model for Fires in the World Trade Center Towers (NISTIR 6879)

May 1, 2002
Author(s)
Ronald G. Rehm, William M. Pitts, Howard R. Baum, D D. Evans, Kuldeep R. Prasad, Kevin B. McGrattan, Glenn P. Forney
Based on preliminary assumptions and analysis, mathematical models have been used to estimate the behavior of the fires in the twin towers of the World Trade Center (WTC) on September 11, 2001. The hijacked-plane collision with each tower produced
