Inhibition of Flames by Condensed-Phase Agents

March 26, 1996
Author(s)
Gregory T. Linteris, D Reinelt
The ban on the production of the fire suppressant CF3Br has created a need for replacement agents. Obvious alternatives are other halogenated hydrocarbons, and much research has recently been devoted to understanding their relative performance and

Office Work Station Heat Release Rate Study: Full Scale vs. Bench Scale

March 26, 1996
Author(s)
Daniel M. Madrzykowski
The National Institute of Standards and Technology (NIST) has conducted a study with office work stations to examine their heat release rates and to determine if the peak heat release rate for a work station can be predicted accurately from cone

Signatures of Smoldering/Pyrolyzing Fires for Multi-Element Detector Evaluation

March 26, 1996
Author(s)
Thomas G. Cleary, William L. Grosshandler, Marc R. Nyden, William J. Rinkinen
Levels of CO, CO2, H2O, hydrocarbons, smoke, temperature and velocity produced in the plumes of smoldering/pyrolyzing wood and smoldering cotton fires are reported, following test protocols described for evaluating automatic fire detection systems. The

Tomographic Reconstruction of Probability Density Functions in Turbulent Flames

March 26, 1996
Author(s)
P Vallikul, R Goulard, C Mavriplis, Marc R. Nyden
Local probability density functions (PDF) of absorption coefficients within turbulent flames have been retrieved from their multi-angular absorption data of path-integrated probability density functions via a series of numerical techniques. First the

Characteristics of Oscillating Buoyant Plumes.

March 13, 1996
Author(s)
B M. Cetegen, K D. Kasper
An experimental study of round buoyant turbulent plumes is described, emphasizing conditions where the flow has lost source momentum and other source distrubances, and has become self preserving. Plume conditions were simulated using dense gas sources in a

Computations of Enhanced Soot Production in Flickering Diffusion Flames.

March 13, 1996
Author(s)
K C. Smyth, C R. Shaddix, C R. Kaplan
Recent experimental measurements of soot volume fraction in a flickering CH4/air diffusion flame show that for conditions in which the tip of the flame is clipped, soot production is ~5 times greater than that measured for a steady flame burning with the

Enhancement of R123 Pool Boiling by the Addition of N-Hexane (NISTIR 5780)

March 1, 1996
Author(s)
Mark A. Kedzierski
This paper presents the heat transfer data used to file international patent WO 94/18282. The data consisted of pool boiling performance of a GEWA-TTM surface for three fluids: (1) pure R123, (2) R123/n-hexane (99/1), and (3) R123/n-hexane (98/2). The heat

Multizone Modeling of Three Residential Indoor Air Quality Control Options

March 1, 1996
Author(s)
Steven J. Emmerich, Andrew K. Persily
The National Institute of Standards and Technology (NIST) performed a preliminary study of the use of central forced-air heating and cooling system modifications to control indoor air quality (IAQ) in residential buildings. The objective of this effort was
