The NIST 3 Megawatt Quantitative Heat Release Rate Facility - Description and Procedures

September 1, 2004
Author(s)
Rodney A. Bryant, Thomas J. Ohlemiller, Erik L. Johnsson, Anthony P. Hamins, B S. Grove, William F. Guthrie, Alexander Maranghides, George W. Mulholland
The 3 Megawatt Heat Release Rate Facility was developed at NIST as a first step toward having broad capabilities for making quantitative large scale fire measurements. Such capabilities will be used at NIST to validate fire models and to develop sub-grid

Development of a Performance Evaluation Facility for Fire Fighting Thermal Imagers

August 1, 2004
Author(s)
Francine K. Amon, Anthony P. Hamins, Jungho Kim, Vytenis Benetis
The Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) is developing a new bench-scale testing facility and methods to evaluate the performance of thermal imagers used by fire fighters to search for

Evaluation of Thermal Imaging Cameras Used in Fire Fighting Applications

August 1, 2004
Author(s)
Francine K. Amon, Anthony P. Hamins
Thermal imaging cameras are rapidly becoming integral equipment for first responders for use in burning structures. Currently there are no standardized test methods or performance metrics available to the users or manufacturers of these instruments. The

Technique for Extrapolating Absorption Coefficient Measurements to High Temperatures

July 25, 2004
Author(s)
Kaoru Wakatsuki, Stephen P. Fuss, Anthony Hamins, Marc R. Nyden
An extrapolation technique that provides semi-quantitative estimates for the infrared absorption coefficients of gaseous fuels at temperatures beyond those for which measurements are generally practical (>700 K) is presented. The new method is based on a

Unwanted Accelerated Burning After Suppressant Delivery

September 2, 2003
Author(s)
Anthony P. Hamins, Kevin B. McGrattan, Glenn P. Forney
In a number of real-scale fire tests, accelerated or enhanced unwanted burning has been observed immediately following the delivery of a fire suppressant. The conditions under which this phenomena occurs, its potential for harm, and its effect on the

Report of Experimental Results for Tests 2,3, and 4 of the International Fire Model Benchmarking and Validation Exercise #3

July 1, 2003
Author(s)
Anthony P. Hamins, Michelle K. Donnelly, Erik L. Johnsson, Alexander Maranghides, George W. Mulholland
As part of its Fire Risk Research Program, the NRC (Nuclear Regulatory Commission) and NIST (National Institute of Standards and Technology) are participating in an International Collaborative Fire Model Project (ICFMP) to assess and validate fire computer

Measurement of Soot Extinction Coefficients

June 16, 2003
Author(s)
J F. Widmann, Jiann C. Yang, George W. Mulholland, Anthony P. Hamins
An experimental apparatus used to obtain soot extinction coefficients in the infrared portion of the electromagnetic spectrum will be presented. Numerous experimental measurements of soot extinction coefficients have been previously obtained at visible

Numerical Modeling of Pool Fires Using LES and Finite Volume Method for Radiation

June 16, 2003
Author(s)
Simo A. Hostikka, Kevin B. McGrattan, Anthony Hamins
The thermal environment in small and moderate-scale pool flames is studied by Large Eddy Simulation and the Finite Volume Method for radiative transport. The spectral dependence of the local absorption coefficient is represented using a simple wide band

Report of Test on Experimental Conditions and Preliminary Results for the International Fire Model Benchmarking And Validation Exercise #3

June 1, 2003
Author(s)
Anthony P. Hamins, Alexander Maranghides, Erik L. Johnsson, Michelle K. Donnelly, Jiann C. Yang, George W. Mulholland

Suppression Limits of Low Strain Rate Non-Premixed Methane Flames

May 1, 2003
Author(s)
Matthew F. Bundy, Anthony P. Hamins, Ki Y. Lee
The suppression of low strain rate non-premixed flames was investigated experimentally in a counterflow configuration for laminar flames with minimal conductive heat losses. This was accomplished by varying the velocity ratio of fuel to oxidizer to adjust

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

Fire Safety Research at NIST

July 1, 2002
Author(s)
Anthony P. Hamins
The Fire Research Division is one of four Divisions in the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST). The Division is composed of approximately 58 full time employees, 25 guest scientists and

Determination of Planck Mean Absorption Coefficients for HBr, HCl, and HF

February 1, 2002
Author(s)
Stephen P. Fuss, Anthony P. Hamins
The Planck mean absorption coefficient has been calculated for HBr HCl, and HF over a temperature range from 300 K-2300 K using data from the 1996 edition of the HITRAN molecular database. Plots of ap versus temperature showed monotonically decreasing
