1. Initial Model for Fires in the World Trade Center Towers (NISTIR 6879)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6879
Published: 5/1/2002
Authors: Ronald G. Rehm, William M Pitts, Howard Richard Baum, D D Evans, Kuldeep R Prasad, Kevin B McGrattan, Glenn P Forney
Abstract: Based on preliminary assumptions and analysis, mathematical models have been used to estimate the behavior of the fires in the twin towers of the World Trade Center (WTC) on September 11, 2001. The hijacked-plane collision with each tower produced s ...

Published: 3/4/2011
Authors: Kuldeep R Prasad, William M Pitts, Jiann C Yang
Abstract: Development of the hydrogen economy will require a better understanding of the potential for fires and explosions associated with the unintended release of hydrogen within a structure. The ability to predict the mixing and dispersion behavior of hydr ...

3. Agent Screening for Halon 1301 Aviation Replacement
Published: 10/20/1993
Authors: William L Grosshandler, Richard George Gann, Anthony P Hamins, Marc R. Nyden, William M Pitts, Jiann C Yang, Michael Russel Zachariah
Abstract: A comprehensive experimental program is described in which eleven gaseous agents and sodium bicarbonate powder have been screened, so that the best three candidates for subsequent full-scale aircraft fire extinguishment evaluation can be identified. ...

4. 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 ...

5. An Investigation of Extinguishment by Thermal Agents Using Detailed Chemical Modeling of Opposed Jet Diffusion Flames
Published: 3/3/2008
Authors: William M Pitts, Jiann C Yang, Rodney A Bryant, Linda G Blevins
Abstract: Detailed chemical kinetic modeling of methane planar opposed-jet laminar diffusion flames burning in air mixed with a variety of thermal agents is used to characterize their effects on maximum flame temperature and extinction behavior. The identific ...

6. An Investigation of Extinguishment by Thermal Agents Using Detailed Chemical Modeling of Opposed-flow Diffusion Flames
Series: Special Publication (NIST SP)
Report Number: 984-4
Published: 4/27/1999
Authors: William M Pitts, L G. Blevins
Abstract: The manufacture of the halons widely used in fire extinguishing systems was banned in 1994 due to their deleterious effect on stratospheric ozone. Since the late 1980s there have been ongoing research efforts to identify replacement agents having com ...

7. Application of Laser-Induced Rayleigh Light Scattering to the Study of Tubulent Mixing.
Series: NIST Interagency/Internal Report (NISTIR)
Published: 2/1/1983
Authors: William M Pitts, Takashi Kashiwagi

8. Application of Thermodynamic and Detailed Chemical Kinetic Modeling to Understanding Combustion Product Generation in Enclosure Fires
Published: 1/1/1994
Author: William M Pitts
Abstract: Experiments in idealized two-layer fire environments have demonstrated that concentrations of carbon monoxide and other gaseous combustion products can be correlated in terms of the global eqivalence ratio. In this paper the results of detailed chemi ...

9. Calibration of Heat Flux Gages for Forum Heat Flux Measurements Working Group Interlaboratory Comparison. Report of Test FR 4015
Series: OTHER
Report Number: 4015
Published: 8/20/2001
Authors: William M Pitts, John R Shields
Abstract: This Report of Test summarizes the results of calibrations of two heat flux gages performed in the Building and Fire Research Laboratory at the National Institute of Standards and Technology on April 16, April 18, and May 7, 2001. The calibrations ar ...

10. Carbon Monoxide Concentration Measurements in Fuel Cell Environments Using Tunable Diode Laser Absorption Spectroscopy (TDLAS): An Assessment
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6810
Published: Date unknown
Author: William M Pitts
Abstract: This report is an analysis of the potential of tunable laser diode absorption spectroscopy (TDLAS) for recording carbon monoxide (CO) concentrations in hydrogen fuel cell environments characteristic of those present during reforming of organic fuels. ...
