81. Thin-Filament Pyrometry in Flickering Laminar Diffusion Flames
Published: 7/28/1996
Author: William M Pitts
Abstract: This paper describes an experimental system for thin-filament pyrometry (TFP) in acoustically phase-locked flickering laminar methane/air diffusion flames. The physical basis of the technique is discussed. The experiment utilizes a 15-mu m beta-SiC f ...

82. Rapid Discharge of a Fire Suppressing Agent
Published: 1/1/1996
Authors: Jiann C Yang, William M Pitts, B D Breuel, William L Grosshandler, W G Cleveland
Abstract: 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 ob ...

83. Real-Time Suppressant Concentration Measurement (NIST SP 890)
Series: Special Publication (NIST SP)
Report Number: 890
Published: 11/1/1995
Authors: William M Pitts, George William Mulholland, B D Breuel, Erik L Johnsson, S Chung, Richard H. Harris Jr., D E Hess
Abstract: 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 ...

84. Species Concentration Measurements (NISTIR 5766)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5766
Published: 11/1/1995
Author: William M Pitts
Abstract: 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 t ...

85. Scaling Compartment Fires - Reduced- and Full-Scale Enclosure Burns.
Published: 9/10/1995
Authors: Nelson P Bryner, Erik L Johnsson, William M Pitts
Abstract: An extensive series of over 140 natural gas fires in a 2/5ths-scale model of a standard room has been previously reported. This work extends the earlier reduced-scale enclosure (RSE) study to a full-scale enclosure (FSE) and focuses on comparing the ...

86. Rayleigh Light Scattering for Concentration Measurements in Turbulent Flows
Published: 7/25/1995
Author: William M Pitts
Abstract: Despite intensive research efforts over a number of years, an understanding of scalar mixing in turbulent flows remains elusive. An understanding is required because turbulent mixing has a pivotal role in a wide variety of natural and technologically ...

87. Combustion Product Formation in Under and Overventilated Full-Scale Enclosure Fires
Published: 4/23/1995
Authors: William M Pitts, Nelson P Bryner, Erik L Johnsson
Abstract: The findings of an extensive series of over 140 natural gas fires in a 2/5ths-scale model of a standard room have been previously reported. The current work extends the earlier reduced-scale enclosure (RSE) study to a full-scale enclosure (FSE) and f ...

88. Global Equivalence Ratio Concept and the Formation Mechanisms of Carbon Monoxide in Enclosure Fires
Published: 1/1/1995
Author: William M Pitts
Abstract: This report summarizes a large number of investigations designed to characterize the formation of carbon monoxide (CO) in enclosures fires - the most important factor in fire deaths. It includes the first complete review and analysis of the studies w ...

89. Carbon Monoxide Production in Compartment Fires: Reduced-Scale Enclosure Test Facility (NISTIR 5568)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5568
Published: 12/1/1994
Authors: Nelson P Bryner, Erik L Johnsson, William M Pitts
Abstract: The formation of carbon monoxide during room or compartment fires has been investigated using natural gas fires burning within a reduced-scale enclosure (RSE), an 0.98 m x 0.98 m x 1.46 m (w x h x d) room with a single door opening centered in the fr ...

90. Carbon Monoxide Production in Compartment Fires: Full-Scale Enclosure Burns (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: Nelson P Bryner, Erik L Johnsson, William M Pitts
Abstract: 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 ...
