81. Upward Flame Spread on Composite Materials
Published: 1/1/1995
Authors: Thomas J. Ohlemiller, Thomas George Cleary
Abstract: Three existing models of upward flame spread were tested against intermediate-scale experiments on a vinyl-ester/glass composite. Characterization of rate of heat release per unit area, needed as input to the models, was obtained at external radiant ...

82. Pipe Flow Characteristics of Alternative Agents for Engine Nacelle Fire Protection
Series: OTHER
Published: 1/1/1995
Authors: Thomas George Cleary, Jiann C Yang, William L Grosshandler, Michelle King, C I Boyer
Abstract: As part of the U.S. Air Force, Army, Navy and FAA Halon Replacement Project at NIST, the pipe flow characteristics were investigated for three engine nacelle alternative candidates: HFC-227ea, HFC-125 and CF31. The flow regime in suppression system ...

83. Experimental Studies on Discharge of Alternative Agent/Nitrogen Mixtures in a Simulated Dry Bay (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: Jiann C Yang, Thomas George Cleary, Roy A McLane, William L Grosshandler
Abstract: 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 ...

84. Pipe Flow Characteristics of Alternative Agent/Nitrogen Mixtures (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: Thomas George Cleary, M D King, Jiann C Yang, William L Grosshandler
Abstract: The evaluation of alternative agents for application in engine nacelle fire protection includes delivery efficiency of agent from a remote storge bottle through piping to the nacelle injection loacation. Present military requirements for halon system ...

85. Upward Flame Spread on Composite Materials
Published: 8/28/1994
Authors: Thomas J. Ohlemiller, Thomas George Cleary
Abstract: The composite materials of interest in this work contain several piles of long, high strength fibers, typically woven in some fixed pattern; the layered multi-ply structure is embedded with an organic polymer resin. Such composites offer a high stre ...

86. Compatibility of Halon Alternatives During Storage
Published: 8/21/1994
Authors: Richard George Gann, Carlos R Beauchamp, Thomas George Cleary, J L. Fink, Richard H. Harris Jr., F Horkay, G B. McKenna, Thomas P Moffat, Marc R. Nyden, Richard D Peacock, Richard E Ricker, Mark R Stoudt, W. K. Waldron
Abstract: A key facet of the evaluation of new fire suppressants is their behavior under pressure and at elevated temperature in a metal storage container with an elastomer seal. In this study, 13 candidate chemicals have been examines: C2F6, C3F8, C4F10, cycl ...

87. Agent Stability Under Storage and Discharge Residue (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: Richard D Peacock, Thomas George Cleary, Richard H. Harris Jr.
Abstract: Halon 1301 is known to be stable in metal containers for many years. Any by-products do not affect its fire suppression effectiveness or result in an unacceptable residue. For candidate replacement chemicals, comparable data are needed, reflecting t ...

88. Flame Suppression Effectiveness (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: Anthony P Hamins, G. Gmurczyk, William L Grosshandler, R. G. Rehwoldt, I Vazquez, Thomas George Cleary, Cary Presser, K Seshadri
Abstract: A flame will be extinguished when the time required for the chain reaction which sustains combustion exceeds the time it takes to replenish the necessary heat and reactants. A characteristic time for reaction can be estimated from the inverse of a gl ...

89. Heat Flux From Flames to Vertical Surfaces
Published: 1/1/1994
Authors: J. G. Quintiere, Thomas George Cleary
Abstract: Dimensional analysis is used to examine heat transfer from flames to vertical surfaces. Configurations include a line fire against a wall, a square burner flame against a wall and in a corner, and window flames impinging on a wall. Dimensionless par ...

90. Influence of Ignition Source on the Flaming Fire Hazard of Upholstered Furniture
Published: 1/1/1994
Authors: Thomas George Cleary, Thomas J. Ohlemiller, K M Villa
Abstract: A set of upholstered chairs constructed from five different fabric/foam combinations was subjected to a variety of ignition sources suggested by fire statistics. The sources included a cigarette, a small match-like flame, an incandescent lamp, a spa ...
