141. Experimental Study of the Optical Properties of Soot and Smoke (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: M Y Choi, George William Mulholland, Anthony P Hamins, Takashi Kashiwagi
Abstract: The accurate measurement of flame-generated particlates is a problem of current interest to researchers in the fire and combustion community. Within the flame, the soot concentration measurement is central to the study of soot growth and for radiant ...

142. Flame Suppression Effectiveness of Halon Alternatives (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: William L Grosshandler, Anthony P Hamins
Abstract: The elimination of new production of halon 1301 has forced the manufacturers, owners, and users of aircraft to search for an alternative. The program described here developed performance screens for candidate agents as a means to identify the best ch ...

143. Model for the Burning of a Horizontal Slab of Wood: Status Report (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: Kenneth David Steckler, Anthony P Hamins, Takashi Kashiwagi
Abstract: We are in the process of developing a burning-rate model for char-forming materials. Currently, the combustion of a horizontal slab of wood, exposed to an external radiant source, is being modeled in terms of two coupled sub-models which simulate gas ...

144. Pool Burning of Silicone Fluids (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: R Buch, Anthony P Hamins, John R Shields, P. Borthwick, R T Baum, Marc R. Nyden, Takashi Kashiwagi
Abstract: Siloxane fluids have a number of industrial applications including use as transformer fluids. The objective of the present study was to improve our understanding of the burning of siloxane fluids. The fluids studied are octamethylcyclotetra siloxane, ...

145. Extinction of Nonpremixed Flames With Halogenated Fire Suppressants
Published: 7/31/1994
Authors: Anthony P Hamins, D Trees, K Seshadri, H K Chelliah
Abstract: An experimental, analytical, and numerical study was performed to elucidate the influence of eleven gaseous agents, considered to be substitutes for CF3Br, on the structure and critical conditions of extinction of diffusion flames burning liquid hydr ...

146. Simultaneous Optical Measurement of Soot Volume Fraction, Temperature and CO2 in Heptane Pool Fire
Published: 7/31/1994
Authors: M Y Choi, Anthony P Hamins, H. Rushmeier, Takashi Kashiwagi
Abstract: Detailed measurements of the temperature, soot volume fraction and CO2 have been performed for a 10 cm diameter heptane fire. In addition, the concentrations of H2O and CO were inferred from generalized state relationships. The heat feedback to the s ...

147. Flame Suppression Effectiveness (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: Anthony P Hamins, G. Gmurczyk, William L Grosshandler, R. G. Rehwoldt, I Vazquez, Thomas George Cleary, Cary Presser, K Seshadri
Abstract: A flame will be extinguished when the time required for the chain reaction which sustains combustion exceeds the time it takes to replenish the necessary heat and reactants. A characteristic time for reaction can be estimated from the inverse of a gl ...

148. Estimate of the Effect of Scale on Radiative Heat Loss Fraction and Combustion Efficiency. Short Communication
Published: 1/1/1994
Authors: Jiann C Yang, Anthony P Hamins, Takashi Kashiwagi
Abstract: The effect of the fire size on radiative heat loss fraction and combustion efficiency was examined by an analysis of scale for pool flames with varying diameter (D). Correlations between D and radiative heat loss fraction or combustion efficiency wer ...

149. Simultaneous Optical Measurement of Soot Volume Fraction and Temperature in Premixed Flames
Published: 1/1/1994
Authors: M Y Choi, Anthony P Hamins, George William Mulholland, Takashi Kashiwagi
Abstract: The performance of a three-wavelength optical probe technique for measuring soot volume fraction and temperature was assessed by conducting experiments in the homogeneous environment of a premixed flame. Using a premixed ethylene/air flame, the tempe ...

150. Comparisons of Soot Volume Fraction Measurements Using Optical and Isokinetic Sampling Techniques
Published: 10/25/1993
Authors: M. Y. Choi, George William Mulholland, Anthony P Hamins, Takashi Kashiwagi
Abstract: In a previous study, the performance of a three-line optical probe technique for measuring soot volume fraction and temperature was assessed by conducting experiments in the path-invariant environment of a premixed flame. In that study, the temperatu ...
