71. Generic Centerline Velocity Decay Curve for Initially Turbulent Axisymmetric Jets
Published: 3/1/1999
Authors: G Papadopoulos, William M Pitts
Abstract: Recently the authors introduced a length scale which effectively collapsed the near field centerline development of velocity and mass fraction for variable density axisymmetric jets whose initial conditions correspond to those of fully developed turb ...

72. Characterization and Identification of Super-Effective Thermal Fire Extinguishing Agents- First Annual Report
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6414
Published: 1/1/1999
Authors: William M Pitts, Jiann C Yang, Marcia L Huber, L G. Blevins
Abstract: The use of halons for fire fighting is being phased out due to their deleterious effects on stratospheric ozone. This report summarizes the first-year findings of a three-year study designed to characterize and identify super-effective thermal fire-f ...

73. Carbon Monoxide Measurement Using a Near-Infrared Tunable Diode Laser (NISTIR 6242)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6242
Published: 10/1/1998
Authors: L G. Blevins, William M Pitts, D S Bomse
Abstract: One important goal of fire research is to study the formation and consumption of chemical species in and around a fire. Instruments which possess rapid temporal response are required for resolving species concentration fluctuations and for studying r ...

74. Temperature Uncertainties for Bare-Bead and Aspirated Thermocouple Measurements in Fire Environments (NISTIR 6242)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6242
Published: 10/1/1998
Authors: William M Pitts, E Braun, Richard D Peacock, Henri E. Mitler, Erik L Johnsson, Paul A Reneke, L G. Blevins
Abstract: Gas-phase temperature is the most ubiquitous measurement recorded in fire environments and plays a central role in understanding of fire behavior. Generally, either bare-bead or sheathed thermcouples are employed. While it is recognized that such the ...

75. Scaling the Near-Field Centerline Mixing Behavior of Axisymmetric Turbulent Jets
Published: 9/1/1998
Authors: G Papadopoulos, William M Pitts
Abstract: Detailed measurements of the centerline mixing behavior in the near field of varible-density jets were performed. Real-time measurements of jet fluid concentration for a propane jet and a methane jet issuing into still air were made utilizing Rayleig ...

76. Effects of Finite Time Response and Soot Deposition on Thin Filament Pyrometry Measurements in Time-Varying Diffusion Flames
Published: 8/2/1998
Authors: William M Pitts, K C Smyth, D Everest
Abstract: Prior work has shown that thin filament pyrometry (TFP) is a powerful approach for making highly precise, spatially and temporally resolved line measurements of temperature in time-varying laminar diffusion flames. The technique has been previously u ...

77. Towards Full Field Scaling of the Centerline Behavior for Initially Turbulent Axisymmetric Jets
Published: 6/21/1998
Authors: G, Papadopoulos, William M Pitts
Abstract: Recently the authors introduced a length scale for effectively collapsing the near field centerline velocity and mass fraction of constant and variable density axisymmetric jets whose initial conditions correspond to those of fully developed turbulen ...

78. Carbon Monoxide Formation Algorithm (NISTIR 6030)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6030
Published: 6/1/1997
Author: William M Pitts
Abstract: This paper discusses an engineering approach for estimating the generation rate of carbon monoxide (CO) within a room containing a fire. The algorithm incorporates four CO formation mechanisms which have been identified in past investigations.

79. Algorithm for Estimating Carbon Monoxide Formation in Enclosure Fires
Published: 3/3/1997
Author: William M Pitts
Abstract: This paper introduces an engineering approach for estimating the generation rate of carbon monoxide (CO) within a room containing a fire. Four CO formation mechanisms: 1) quenching of a turbulent fire plume upon entering a rich upper layer, 2) mixing ...

80. Mixing Behavior of Absolutely Unstable Axisymmetric Shear Layers Forming Side Jets
Published: 1/1/1997
Authors: William M Pitts, A W Johnson
Abstract: Recently it has been shown that low-density axisymmetric jets can become absolutely unstable and develop highly coherent vortical structures in the near-field shear layer. These jets have several unusual properties when compared to jets which are con ...
