Temperature Uncertainties for Bare-Bead and Aspirated Thermocouple Measurements in Fire Environments

July 1, 2003

Author(s)

William M. Pitts, E Braun, Richard D. Peacock, Henri E. Mitler, Erik L. Johnsson, Paul A. Reneke, L G. Blevins

Temperature measurements have been made for natural-gas and heptane fires in a reduced-scale enclosure using a variety of bare-bead and aspirated thermocouples in order to characterize the uncertainties. The focus is the role of radiative heat transfer and

Extended Abstracts and Presentations from the Workshop on Fire Growth and Spread on Object, March 4-6, 2002, National Institute of Standards and Technology

Overview of the World Trade Center

Flow Characterization of Flickering Methane/Air Diffusion Flames Using Particle Image Velocimetry

September 1, 2002

Author(s)

G Papadopoulos, Rodney A. Bryant, William M. Pitts

Phase-resolved measurements of the velocity field in acoustically forced, flickering laminar co-flowing methane/air diffusion flames have been made. Identical flames have been studied extensively in the past in order to characterize the effects of the

Initial Model for Fires in the World Trade Center Towers

May 1, 2002

Author(s)

Ronald G. Rehm, William M. Pitts, D D. Evans, Kuldeep R. Prasad, Kevin B. McGrattan, Glenn P. Forney

Mathematical models have been used to provide an initial estimate the behavior of the fires in the twin towers of the World Trade Center (WTC) on September 11, 2001. Available photographs and videos have provided an initial estimate of the exterior damage

Initial Model for Fires in the World Trade Center Towers (NISTIR 6879)

May 1, 2002

Author(s)

Ronald G. Rehm, William M. Pitts, Howard R. Baum, D D. Evans, Kuldeep R. Prasad, Kevin B. McGrattan, Glenn P. Forney

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

August 20, 2001

Author(s)

William M. Pitts, John R. Shields

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 are part

NIST/BFRL CALIBRATION SYSTEM FOR HEAT-FLUX GAGES

August 6, 2001

Author(s)

William M. Pitts, James R. Lawson, John R. Shields

This report of test describes a heat-flux gage calibration system that was developed at the National Bureau of Standards during the 1970s. It is based on a commercial radiant heater incorporating a tungsten lamp and elliptical mirror. A kaleidoscope flux
