Global Properties of Gaseous Pool Fires

July 28, 1996
Author(s)
Anthony P. Hamins, K Konishi, Robert P. Borthwick, Takashi Kashiwagi
Global flame properties were measured as a function of fuel mass in a series of experiments conducted on gaseous pool fires burning in a quiescent environment. The measurements included radiative heat loss, heat transfer to the burner, and sensible

Suppression of a Baffle-Stabilized Spray Flame by Halogenated Agents

July 28, 1996
Author(s)
Anthony P. Hamins, Cary Presser, L Melton
A series of experiments was conducted on baffle-stabilized spray flames in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame suppression. Measurements were made of the agent mass

Thin-Filament Pyrometry in Flickering Laminar Diffusion Flames

July 28, 1996
Author(s)
William M. Pitts
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 fiber

104-fold isotope effect: Vibrational predissociation in ArDF

July 1, 1996
Author(s)
S Davis, J T. Farrell, D T. Anderson, David Nesbitt
High-resolution sub-Doppler line shapes for ArDf excited into the v DF=1 manifold are recorded using a turnable laser/slit supersonic expantion near-infrared spectrometer. Direct spectroscopic evidence is obtained for vibrational predissociation (τless

Benefits and Costs of Research: Two Case Studies in Building Technology.

July 1, 1996
Author(s)
Robert E. Chapman, S K. Fuller
The National Institute of Standards and Technology (NIST) is improving its resource allocation process by doing "microstudies" of its research impacts on society. This report is the outgrowth of a series of microstudies prepared by NIST's Building and Fire

Charge-transfer rate constants for N+/2 (v=0-4) with Ar at thermal energies

July 1, 1996
Author(s)
S Kato, J A. de Gouw, C D. Lin, V M. Bierbaum, S R. Leone
Rate constants for the charge-transfer reaction N 2 +(V)+ Ar>N 2+Ar + are measured at thermal energies as a function of initial vibrational excitation by laser-induced fluorescence. The reaction is slow for v=0, whereas the rate constants for v=1-4 are

January 17, 1995 Hyogoken-Nanbu (Kobe) Earthquake: Performance of Structures, Lifelines, and Fire Protection Systems (NIST SP 901)

July 1, 1996
Author(s)
R M. Chung, D B. Ballantyne, E Comeau, T L. Holzer, Daniel M. Madrzykowski, A J. Schiff, William C. Stone, J Wilcoski, R. D. Borcherdt, J D. Cooper, Hai S. Lew, Jack P. Moehle, L H. Sheng, A W. Taylor, I Bucker, John(Jack) R. Hayes Jr., E V. Leyendecker, T O'Rourke, M P. Singh, M Whitney
The January 17, 1995 Hyogoken-Nanbu earthquake of magnitude 7.2 in JMA scale (Mw = 6.9), which struck Kobe, Japan and its surrounding area was the most severe earthquake to affect that region this century. The earthquake resulted in more than 6,000 deaths

Lorentz-Lorenz Shift in an Inhomogeneously Broadened Medium

July 1, 1996
Author(s)
J Guo, Alan Gallagher, J W. Cooper
A simple calculation shows that the Lorentz-Lorenz shift due to the local field correction remains significant in situations where the inhomogeneous broadening of a medium exceeds the homogeneous broadening. As an illustration, the calculated selective
