Acid Gas Production in Inhibited Premixed Flames (NISTIR 5499)

September 1, 1994

Author(s)

Gregory T. Linteris, M D. King, A Liu

Halogenated fire extinguishing agents such as CF3Br decompose in flames to form hydrogen halides such as HF and HBr and other toxic and corrosive products. Possible replacements for halon 1301 are required in significantly higher concentrations to

Burning Rate of Premixed Methane-Air Flames Inhibited by Fluorinated Hydrocarbons. [Abstract Only] (NISTIR 5499)

September 1, 1994

Author(s)

Gregory T. Linteris, L Truett

The agents which are currently being considered as replacements for fire suppressant agent CF3Br are mostly fluorinated hydrocarbons and perfluorinated alkanes. This abstract describes measurements of the reduction in burning rate of premixed methane-air

Carbon Monoxide Production in Compartment Fires: Full-Scale Enclosure Burns (NISTIR 5499)

September 1, 1994

Author(s)

Nelson P. Bryner, Erik L. Johnsson, William M. Pitts

Recent studies attribute a large percentage of fire injuries and deaths to the generation of carbon monoxide (CO) and indicate that in roughly two-thirds of the fire deaths the fire victims have fatal or incapacitating levels of carboxyhemoglobin in their

Comparison of FFT Fingerprint Filtering Methods for Neural Network Classification

Engineering Algorithm for the Estimation of Carbon Monoxide Generation in Enclosure Fires (NISTIR 5499)

September 1, 1994

Author(s)

William M. Pitts

Roughly two thirds of all deaths resulting from enclosure fires can be attributed to the presence of carbon monoxide (CO) which is the dominant toxicant in fire deaths. A long-term program (Carbon Monoxide production and Prediction Project) at the Building

Experimental Studies on Discharge of Alternative Agent/Nitrogen Mixtures in a Simulated Dry Bay (NISTIR 5499)

September 1, 1994

Author(s)

Jiann C. Yang, Thomas G. Cleary, Roy A. McLane, William L. Grosshandler

Discharge of the three selected alternative agents for aircraft dry bay fire protection has been conducted in a simulated dry bay (i.e., in an unconfined space). The three selected agents are CF3I, FC-218, and HFC-125. Halon 1301 is also included in the

Experimental Study of the Optical Properties of Soot and Smoke (NISTIR 5499)

September 1, 1994

Author(s)

M Y. Choi, George W. Mulholland, Anthony Hamins, Takashi Kashiwagi

The accurate measurement of flame-generated particlates is a problem of current interest to researchers in the fire and combustion community. Within the flame, the soot concentration measurement is central to the study of soot growth and for radiant

Fire-Induced Mass Flow Into a Reduced-Scale Enclosure (NISTIR 5499)

September 1, 1994

Author(s)

Erik L. Johnsson, Nelson P. Bryner, William M. Pitts

Enclosure fires are of great interest because of the resulting loss of life and property, yet the fluid dynamic and chemical behaviors of fires within enclosures are still not well understood. In recent decades, it has become clear that burning rates, fire

Flame Suppression Effectiveness of Halon Alternatives (NISTIR 5499)

September 1, 1994

Author(s)

William L. Grosshandler, Anthony P. Hamins

The elimination of new production of halon 1301 has forced the manufacturers, owners, and users of aircraft to search for an alternative. The program described here developed performance screens for candidate agents as a means to identify the best

Halon 1301 Surrogates for Engine Nacelle Fire Suppression System Certification (NISTIR 5499)

September 1, 1994

Author(s)

C A. Womeldorf, Jiann C. Yang, William L. Grosshandler

Until recently halon 1301 has been regularly discharged in Navy aircraft engine nacelles to certify that the fire suppression systems distribute the fire suppressant effectively. Halon 1301 can no longer be used in this manner because of its high ozone

Laminar Flame Speeds of CF3H-Propane-Air Mixtures at Elevated Pressures (NISTIR 5499)

September 1, 1994

Author(s)

S Hochgreb, Y. E. Hsin, Gregory T. Linteris

A fundamental property of interest in characterizing the effectiveness of fire suppressants is the effect of addition of inhibitors on the laminar flame speed of a fuel as a function of pressure and temperature of the unburned mixture. The effects of CF3H

Model for the Burning of a Horizontal Slab of Wood: Status Report (NISTIR 5499)

September 1, 1994

Author(s)

Kenneth D. Steckler, Anthony P. Hamins, Takashi Kashiwagi

We are in the process of developing a burning-rate model for char-forming materials. Currently, the combustion of a horizontal slab of wood, exposed to an external radiant source, is being modeled in terms of two coupled sub-models which simulate gas and
