Thermal Radiation From Large Pool Fires (NISTIR 6546)

November 1, 2000
Author(s)
Kevin B. McGrattan, Howard R. Baum, Anthony P. Hamins
In order to protect people and combustible structures from the thermal radiation emitted by a large fire, the Department of Housing and Urban Development (HUD) has established thermal radiation flux levels of 31.5 kW/m2 (10,000 Btu/h/ft2) for buildings and

Fire Dynamics Simulator: Technical Reference Guide (NISTIR 6467)

January 1, 2000
Author(s)
Kevin B. McGrattan, Howard R. Baum, Ronald G. Rehm, Anthony P. Hamins, Glenn P. Forney
The idea that the dynamics of a fire might be studied numerically dates back to the beginning of the computer age. Indeed, the fundamental conservation equations governing fluid dynamics, heat transfer, and combustion were first written down over a century

Fire Dynamics Simulator: User's Manual (NISTIR 6469)

January 1, 2000
Author(s)
Kevin B. McGrattan, Glenn P. Forney
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

Suppression of a Non-Premixed Flame Behind a Step

January 1, 2000
Author(s)
William L. Grosshandler, R Charagundla, Anthony P. Hamins, Kevin B. McGrattan, Cary Presser
Because of its many positive attributes, halon 1301 or trifluorobromomethane (CF 3Br), has been used as a fire extinguishing agent in many applications, including aircraft, ships, and specialized structures. Due to its high ozone depletion potential

Modeling of Sprinkler, Vent and Draft Curtain Interaction

July 5, 1999
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, Glenn P. Forney
The International Fire Sprinkler, Smoke & Heat Vent, Draft Curtain Fire Test Project organized by the National Fire Protection Research Foundation (NFPRF) brought together a group of industrial sponsors to support and plan a series of large scale tests to

Numerical Simulation of Sprinkler Performance

February 24, 1999
Author(s)
Kevin B. McGrattan, Glenn P. Forney
Rapidly, changing building designs, uses, materials, contents, fire protection and the general intermix of industrial/commercial and residential occupancies has created a need to understand the potential hazards and losses from fires and performance of

Transient Agent, Recirculating Pool Fire (TARPF) Suppression Screen (NISTIR 6242)

October 1, 1998
Author(s)
William L. Grosshandler, Anthony P. Hamins, Kevin B. McGrattan, Cary Presser
The amount of a gaseous agent required to extinguish fires in full-scale engine nacelle tests varies greatly with the geometry of the fixture and the manner in which the flame is stabilized. It has been observed that if the test is designed to allow fuel

Using Bench Scale Fire Measurements in Large Scale Simulations (NISTIR 6242)

October 1, 1998
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, L G. Blevins
A program is underwat at NIST to develop a numerical field model, referred to as the Industrial Fire Simulator (IFS), to simulate large scale fire phenomena. Because the model is intended to simulate fire flows within buildings whose volumes are on the

Sprinkler, Smoke and Heat Vent, Draft Curtain Interaction: Large Scale Experiments and Model Development. International Fire Sprinkler-Smoke and Heat Vent-Draft Curtain Fire Test Project (NISTIR 6196-1)

September 1, 1998
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, D W. Stroup
The International Sprinkler, Smoke and Heat Vent, Draft Curtain Fire Test Project organized by the National Fire Protection Research Coundation (NFPRF) has brought together a group of industrial sponsors to study the interaction of sprinklers with roof

Sprinklers, Vent, and Draft Curtain Interaction: Modeling and Experiment

February 25, 1998
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, D. D. Evans
The second and most recent application of the NIST Industrial Fire Simulation (IFS) System is to predict the performance of sprinklers, draft curtains and roof vents in storage facilities and retail spaces. The IFS System is a series of computational fluid

Application of a Large Eddy Simulation Model to Study Room Airflow.

January 1, 1998
Author(s)
Steven J. Emmerich, Kevin B. McGrattan
A three-dimensional, large eddy simulation (LES) model developed for studying the transport of smoke and hot gases during afire in an enclosure is described. The model uses finite digerence techniques to solve the Navier-Stokes equations with an approach

Suppression of Engine Nacelle Fires (NIST SP 890)

November 1, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary, P. Borthwick, N Gorchkov, Kevin B. McGrattan, Glenn P. Forney, William L. Grosshandler, Cary Presser, L Melton
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

September 10, 1995
Author(s)
Glenn P. Forney, Kevin B. McGrattan
Over the last twenty years there has been much debate concerning the interaction of sprinklers and draft curtains in large storage facilities. At issue is whether or not the two fire protection systems are mutually beneficial. It has been suggested that in
