Radiometric Model of the Transmission Cell-Reciprocal Nephelometer

January 1, 1994
Author(s)
George W. Mulholland, Nelson P. Bryner
A radiometric model has been developed to assess the effects of angular truncation, finite size of the detector, and angle response characteristics of the cosine sensor on the measurement of the total scattering coefficient by a transmission cell

Ultrafine Combustion Aerosol Generator

January 1, 1992
Author(s)
Thomas G. Cleary, George W. Mulholland, Lewis K. Ives, Robert A. Fletcher, J. W. Gentry
We are able to produce a narrowly distributed combustion aerosol with a mean particle size of about 10 nm by operating a laminar diffusion burner with acetylene fuel in the nominal "presooting" condition. Number concentrations of approximately 106

Analysis of Smoke Samples From Oil Well Fires in Kuwait. Report of Test (FR 3985)

June 20, 1991
Author(s)
George W. Mulholland, Bruce A. Benner Jr, Robert A. Fletcher, Eric B. Steel, Stephen A. Wise, Willie E. May, Daniel M. Madrzykowski, David J. Evans
This report describes results from a preliminary series of measurements concerning the smoke production from the Kuwait oil well fires. Detailed chemical analysis of the smoke is being carried out for determination of the fraction of ambient aerosol

Smoke Emission and Burning Rates for Urban Structures

January 1, 1991
Author(s)
Nelson P. Bryner, George W. Mulholland
Cribs, ordered arrays of sticks, were burned to mimic post-nuclear building fires. As the packing density of the cribs was increased to simulate blast damage, the smoke yield increased and the smoke changed from strongly light absorbing to whitish in color

Laboratory Studies of Smoke Properties at NIST Past, Present, and Future

November 1, 1990
Author(s)
George W. Mulholland, Nelson P. Bryner
Burn facilities have been developed at NIST to measure the yield and optical properties of smoke at two fire scales. The small scale apparatus is used for burning samples about 10 cm in diameter (soup bowl size) and an intermediate scale apparatus is used

Combustion of Oil on Water.

November 1, 1987
Author(s)
Howard R. Baum, George W. Mulholland, D D. Evans, B J. McCaffrey, M F. Harkleroad, W F. Manders
This report contains the results of measurements performed on both 0.4 m and 0.6 m diameter pool fires produced by burning a layer of Prudhoe Bay crude oil supported by a thermally deep layer of water. Both steady and vigorous burning caused by boiling of
