Agent Screening for Halon 1301 Aviation Replacement

October 20, 1993
Author(s)
William L. Grosshandler, Richard G. Gann, Anthony P. Hamins, Marc R. Nyden, William M. Pitts, Jiann C. Yang, Michael R. Zachariah
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

Structure of Inhibited Counterflowing Nonpremixed Flames

May 11, 1993
Author(s)
Anthony P. Hamins, M H. Yang, I K. Puri
Recent international agreements call for a halt to the manufacture of CF3Br (Halon 1301), a commonly used halon fire suppressant, due to its high ozone-depletion potential. Ideally, the search for replacement compounds should be guided by fundamental

Extinction of Inhibited, Stretched and Diluted Counterflowing Flames

March 15, 1993
Author(s)
M H. Yang, I K. Puri, Anthony Hamins
It has been shown that a criteria for flame extinction can be described by the Damkohler Number which is the ratio of a characteristic flow or diffusion time to a characteristic chemical reaction time. As the Damkohler Number is reduced the fuel burning

Simultaneous Optical Measurement of Soot Volume Fraction and Temperature

March 15, 1993
Author(s)
M. Y. Choi, Anthony Hamins, Takashi Kashiwagi
Radiative heat transfer processes in large fires govern the burning rate, the flame spread rate and the potential for fire hazards. These processes are controlled by the detailed structure of the fire, primarily the temperature and soot distributions. In

Soot

January 1, 1993
Author(s)
Anthony P. Hamins
The major source of carbonaceous soot released into the environment is from the incomplete combustion of fossil fuels and other organic matter. Principal sources of soot emissions are coal burning furnaces, refuse burning, code production processes, wood
