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

Generation and Transport of Smoke Components

April 1, 2004
Author(s)
Kathryn M. Butler, George W. Mulholland
Smoke is a mixture of gases and suspended particulate matter, or aerosols. The nature of the aerosol component of smoke can play a significant role in the lethal and sublethal effects on people. This paper presents the current state of knowledge about

Particle Size Measurements for Spheres With Diameters of 50 nm to 400 nm

August 1, 2003
Author(s)
Michelle K. Donnelly, George W. Mulholland
This paper describes a calibration service NIST is offering that measures the effective diameter of particles suspended in liquids using electrical differential mobility analysis. Measurements are for particles with diameters in the range of 50 nm to 400

Cosolvent-assisted Spray Pyrolysis for the Generation of Metal Particles

July 1, 2003
Author(s)
Valeri I. Babushok, S H. Ehrman, Thomas Germer, Jae H. Kim, George W. Mulholland
A co-solvent assisted spray pyrolysis process was developed for the formation of pure metal particles from metal salt precursors without the direct addition of hydrogen or other reducing gas. Generation of pure copper and nickelparticles from aqueous

Measurement of the Optical Extinction Coefficients of Post-Flame Soot in the Infrared

July 1, 2003
Author(s)
J F. Widmann, Jiann C. Yang, Samuel L. Manzello, George W. Mulholland
The optical extinction coefficients of post-flame soot have been measured in the wavelength range 2.8 micrometers to 4.1 micrometers. A laminar diffusion burner was combined with an infrared spectrograph and gravimetric measurements to determine the mass

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
