CFD Modeling of Fire

January 11, 2012
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka, Howard R. Baum
An overview of a methodology for simulating fires and other thermally-driven, low-speed flows is presented. The model employs a number of simplifications of the governing equations that allow for relatively fast simulations of practical fire scenarios. The

A Note on Visualizing Smoke and Fire

August 15, 2011
Author(s)
Glenn P. Forney
Realistic visualization methods are important for applications where one wishes to observe data effects rather than examine data quantitatively. This note documents how the radiation transport equation (RTE) and associated numerical algorithms are used by

MODELING THE BURNING OF COMPLICATED OBJECTS USING LAGRANGIAN PARTICLES

July 4, 2010
Author(s)
Kevin B. McGrattan, Randall J. McDermott, William E. Mell, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka
A methodology is described for representing complicated objects within a computational fluid dynamics model. These objects are typically collections of similar items that are too small to define on the numerical grid that is used to solve the governing

Smokeview: A Visualization Tool for Understanding Fire Dynamics

December 1, 2008
Author(s)
Glenn P. Forney
The purpose of fire modeling is to gain a better insight into fire dynamics and how it impacts fire safety -- not to generate large amounts of data. Gaining this insight requires visualization tools that display what the numbers generated by the model

Visualization, A Tool For Understanding Fire Dynamics

July 1, 2007
Author(s)
Glenn P. Forney
Computational tools have been developed at the National Institute of Standards and Technology (NIST) for modeling fire spread and smoke transport. These models include FDS (Fire Dynamics Simulator) for modeling fire spread and smoke transport and Smokeview

Visualization and Modeling of Smoke Transport Over Landscape Scales

May 1, 2007
Author(s)
Glenn P. Forney, William E. Mell
Computational tools have been developed at the National Institute of Standards and Technology (NIST) for modeling fire spread and smoke transport. These tools have been adapted to address fire scenarios that occur in the wildland urban interface (WUI) over

Computer Simulation of the Fires in the World Trade Center Towers. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5F) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Kevin B. McGrattan, Charles E. Bouldin, Glenn P. Forney
This report presents the results of numerical simulations of the fires in World Trade Center (WTC) 1 and WTC 2 on September 11, 2001. The calculations were performed with the National Institute of Standards and Technology (NIST) Fire Dynamics Simulator, a

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
