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

The NIST 3 Megawatt Quantitative Heat Release Rate Facility

January 12, 2004
Author(s)
Rodney A. Bryant, Thomas J. Ohlemiller, Erik L. Johnsson, Anthony P. Hamins, B S. Grove, William F. Guthrie, Alexander Maranghides
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

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

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
