National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Structure and Radiation Properties of Pool Fires.

PB94193802

Publication Date	1992
Personal Author	Klassen, M.; Gore, J. P.
Page Count	156
Abstract	An experimental and theoretical study of radiative feedback, burning rates, radiative heat loss fractions, and flame heights for pool fires with diameters ranging from 4.6 cm to 100 cm was completed. Transient measurements of soot and temperature distributions were obtained in 7.1 cm and 30 cm heptane and toluene fires using a three-wavelength emission/absorption probe. The heat release rates of the fires varied from 0.6 kW to 2,166 kW allowing a study over a wide range. A variety of fuels were tried but most of the measurements were restricted to methanol, heptane, and toluene as representatives of the alcohols, paraffins and aromatics. Radiative feedback was measured using a new in situ purged optical probe inserted at the level of the fuel surface. Measurements of reflection of energy from the fuel surface were also obtained.
