Heat Release Mechanisms in Inhibited Laminar Counterflow Flames (Journal)

January 1, 1996
Author(s)
Ki Y. Lee, Don J. Cha, Anthony Hamins, I K. Puri
Due to the participation of inhibitors in flame chemistry, it is difficult to concurrently characterize the complex interaction between their cooling action, and the chemical inhibition (which decrease temperature), and their contribution of heat release

Rapid Discharge of a Fire Suppressing Agent

January 1, 1996
Author(s)
Jiann C. Yang, William M. Pitts, B D. Breuel, William L. Grosshandler, W G. Cleveland
This paper describes an experimental method to study the rapid discharge of a fire suppressant (C3F8) from a pressurized vessel. Experimental observations inside and at the exit of the vessel were made using high-speed photography. Boiling was not observed

THE INFLUENCE OF HALOGENATED FIRE SUPPRESSANTS ON THE COMBUSTION OF C1-C2 HYDROCARBONS

January 1, 1996
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., T Noto, Anthony P. Hamins, Wing Tsang, A W. Miziolek
Numerical simulations of the combustion of a number of fuels; (CH,, CH,OH, C2H,, GH, and C&J in air, in the presence and absence of fire suppressants, (CF,Br, CFJ, CF,, Cm3, GF6, and QF5H) have been carried out The simulations considered reactions in a

Agent Stability Under Storage (NIST SP 890)

November 1, 1995
Author(s)
Richard H. Harris Jr.
Significant losses in fire suppression effectiveness and increases in toxicity are possible if a fire extinguishing agent degrades during multi-year storage. Halon 1301 is known to be stable in metal containers for many years, and any trace degradation

Introductory Remarks (NISTIR 5766)

November 1, 1995
Author(s)
Jiann C. Yang
Objectives of the Workshop: (1) to identify what we know and don't know in gas generator technology for fire suppression; (2) to identify future research areas in gas generator technology for fire suppression; (3) to identify potential users and address

Optimization of System Discharge (NIST SP 890)

November 1, 1995
Author(s)
Jiann C. Yang, Thomas G. Cleary, I Vazquez, C I. Boyer, M D. King, B D. Breuel, C A. Womeldorf, William L. Grosshandler, Marcia L. Huber, L Weber, G. Gmurczyk
Current aircraft fire suppression bottles for dry bay and engine nacelle applications, which are designed to meet Military Specification MIL-C-22284A (proof pressure of 9.62 MPa and minimum burst pressure of 12.37 MPa), are normally filled with liquid

Photodegradation of CF3I (NIST SP 890)

November 1, 1995
Author(s)
Marc R. Nyden
CF3I has been identified as a leading candidate for the replacement of halon fire extinguishing agents because of its high degree of effectiveness as a flame suppressant and its short tropospheric lifetime and low ozone depeletion potential. Although this

Prediction of HF Formation During Suppression (NIST SP 890)

November 1, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
The acid gases hydrogen fluoride, hydrogen chloride, and hydrogen bromide (HX, where X denotes a halogen), are thought to be the most damaging and dangerous of the potential decomposition products, and much study has been devoted to determining the amounts

Real-Time Suppressant Concentration Measurement (NIST SP 890)

November 1, 1995
Author(s)
William M. Pitts, George W. Mulholland, B D. Breuel, Erik L. Johnsson, S Chung, Richard H. Harris Jr., D E. Hess
The development and testing of two approaches for recording real-time measurements (millisecond time resolution) of concentration for halon alternatives are summarized. Discussions of the background necessary to understand their operation is included. The

Solid Propellant Gas Generators: Proceedings of the 1995 Workshop (NISTIR 5766)

November 1, 1995
Author(s)
Jiann C. Yang, William L. Grosshandler
A workshop on solid propellant gas generators was held on June 28-29, 1995 at the National Institute of Standards and Technology under the sponsorship of the Building and Fire Research Laboratory. Gas generator technology was first proposed as alternative

Species Concentration Measurements (NISTIR 5766)

November 1, 1995
Author(s)
William M. Pitts
The objective if this effort is to evaluate possible methods for real-time measurements of concentrations of alternative fire extinguishing agents for dry-bay and nacelle fire applications. If one or more feasible approaches are identified early in the

Suppression of Engine Nacelle Fires (NIST SP 890)

November 1, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary, P. Borthwick, N Gorchkov, Kevin B. McGrattan, Glenn P. Forney, William L. Grosshandler, Cary Presser, L Melton
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Storage and Discharge Characteristics of Halon Alternatives

October 21, 1995
Author(s)
Jiann C. Yang, Thomas G. Cleary, I Vazquez, C I. Boyer, M D. King, B D. Breuel, Marcia L. Huber, L Weber
Three important issues regarding the use of halon alternatives for in-flight fire protection applications were studied as part of the current halon alternative research program at the National Institute of Standards and Technology (NIST): (1) the

Suppression Criteria in Engine Nacelle Fires

October 21, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Effect of CF3H and CF3Br on Laminar Diffusion Flames in Normal and Microgravity

October 16, 1995
Author(s)
B. A. VanDerWege, M T. Bush, S Hochgreb, Gregory T. Linteris
Due to the ban on production of bromotrifluoromethane (CF3Br) because of its high ozone destruction potential, there has been recent interest in finding a replacement for it for fire extinguishing applications. While a variety of potential replacements are
