151. Extinction of Inhibited, Stretched and Diluted Counterflowing Flames
M H Yang, I K Puri, Anthony P 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 burn ...
152. Simultaneous Optical Measurement of Soot Volume Fraction and Temperature
M. Y. Choi, Anthony P 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 ...
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, ...
154. Behavior of Primary Radicals During Thermal Degradation of Poly(Methyl Methacrylate)
Takashi Kashiwagi, A Inabi, Anthony P Hamins
The behavior of the primary radicals formed from the random scission of anionically polymerized poly(methyl methacrylate). PMMA, during thermal degradation is investigated by a theoretical and experimental study. The theoretically calculated relation ...
155. Measurements and Simulations of Low Strain Rate Non-Premixed Methane Flame Extinction
Anthony P Hamins, Matthew F Bundy, C B Oh
The extinction and structure of non-premixed flames were investigated through the comparison of experiments and calculations using a counterflow configuration. Experiments were conducted at the NASA Glenn Research Center s 2.2 s drop tower to attain ...
