Energy Balance in a Large Compartment Fire. (POSTER ABSTRACTS)

September 18, 2005
Author(s)
Anthony P. Hamins, Erik L. Johnsson, Michelle K. Donnelly
The experiments described here were part of an international collaborative project to assess and validate fire computer codes for nuclear power plant applications. Understanding the distribution of energy released by a fire is important for testing the

Experiments and Modeling of Structural Steel Elements Exposed to a Fire. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5B) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Anthony P. Hamins, Alexander Maranghides, Kevin B. McGrattan, Erik L. Johnsson, Thomas J. Ohlemiller, Michelle K. Donnelly, Jiann C. Yang, George W. Mulholland, Kuldeep R. Prasad, S R. Kukuck, Robert Anleitner, Therese P. McAllister
Reconstructing the fires and their impact on structural components in the World Trade Center (WTC) buildings on September 11, 2001, requires extensive use of computational models. For the use of such models to be a viable investigative tool, it is

CF3I Stability Under Storage.

December 1, 2004
Author(s)
Michelle K. Donnelly, Richard H. Harris Jr., Jiann C. Yang
This research investigates the stability of iodotrifluoromethane (CF3I) during storage. For CF3I to be used as a fire extinguishing agent, it must be able to be stored for long periods of time at high pressure in metal containers without degrading and

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

Using Sensor Signals to Analyze Fires

January 23, 2002
Author(s)
William D. Davis, Thomas G. Cleary, Michelle K. Donnelly, S. D. Hellerman
Building fire sensors are capable of supplying substantially more information to the fire service than just the simple detection of a possible fire. Nelson, in 1984, recognized the importance of tying all the building sensors to a smart fire panel. In

Suppression of Fires Exposed to an External Radiant Flux

December 1, 2001
Author(s)
Michelle K. Donnelly, William L. Grosshandler
When materials are burning in the presence of a continuous, external energy source, they are often more difficult to extinguish and may require an increase in suppression agent to extinguish the fire. This situation could exist for class C fires involving
