A Simple Model of Fireball Dynamics

February 19, 2017
Author(s)
Howard R. Baum, Ronald G. Rehm
An analytical model of the initial expansion of a fireball is presented.The model is based on an exact solution of the low Mach number combustion equations in the form initially proposed by the authors. The equations consist of the conservation of mass

A Technical Guide for Smokeview Version 5

February 19, 2017
Author(s)
Glenn P. Forney
Smokeview is a software tool designed to visualize numerical calculations generated by the NIST Fire Dynamics Simulator (FDS), a computational fluid dynamics (CFD) model of fire-driven fluid flow. This report documents some of the technical details and

Advances in Thermal Imaging Technology in the First Responder Arena

February 19, 2017
Author(s)
Francine K. Amon, Nelson P. Bryner
The Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) has been conducting research that will provide a quantifiable physical and scientific basis upon which industry standards for imaging performance

Aerodynamic Damping in the Along-Wind Response of a Tall Building

February 19, 2017
Author(s)
Rene D. Gabbai, Emil Simiu
We present an estimate of the aerodynamic damping that affects the along-wind response of an isolated tall building in suburban terrain. The evaluation uses measurements of the external pressures on the windward and leeward faces under wind normal to a

AEX XML Schema Reference Guide

February 19, 2017
Author(s)
Mark E. Palmer, M Burns, T L. Teague, Mary Turton, Rurik Turton
The AEX XML Schema Reference Guide summarizes the design principles and the structures of the AEX (Automating Equipment Information eXchange) XML schemas, guidance for making schema extensions and usage guidance for those who wish to deploy the AEX schemas

Alert Categorization, Revision 1.0

February 19, 2017
Author(s)
Alan B. Vinh
There are many types of sensor devices available in today s market with many still in development. These devices send signals representing the detection of entities such as temperature and smoke. With the availability of sensor devices monitoring various

Assessment of the Structural Fire Performance of Buildings

February 19, 2017
Author(s)
Richard W. Bukowski
The fire-induced collapse of the World Trade Center (WTC) buildings 1, 2, and 7 on 11 September 2001 demonstrated the need for engineering methods to predict the structural fire performance of buildings when subjected to arbitrary design fires and to

Benefits and Costs of Research: A Case Study of Fire Dynamics Simulation

February 19, 2017
Author(s)
Barbara C. Lippiatt
The Fire Dynamics Simulation (FDS) research program at the National Institute of Standards and Technology (NIST) has produced software that simulates fire spread and the response of a given sprinkler system. At the request of warehouse property owners, the

BFRL Publications, 2001. Volume 1 and Volume 2

February 19, 2017
Author(s)
Star R. Burgess, Kathleen C. Whisner, Glenn P. Forney, Paul A. Reneke
Welcome to BFRL Publications, 2001. These two CD-ROMs contain publications produced by BFRL staff, publications resulting from contracts or grants with BFRL and publications contained in proceedings from BFRL sponsored conferences or workshops. The Volume

Calculations of the Energy of Mixing Carbon Nanotubes With Polymers

February 19, 2017
Author(s)
Marc R. Nyden, Stanislav Stoliarov
A method for estimating the free energy of mixing CNTs with polymers is presented. The formation of the nanocomposite is analyzed in terms of a simple path in which the nanotubes are exfoliated from a bundle and dispersed in a distorted polymer with
