Global Properties of Gaseous Pool Fires

July 28, 1996
Author(s)
Anthony P. Hamins, K Konishi, Robert P. Borthwick, Takashi Kashiwagi
Global flame properties were measured as a function of fuel mass in a series of experiments conducted on gaseous pool fires burning in a quiescent environment. The measurements included radiative heat loss, heat transfer to the burner, and sensible

Suppression of a Baffle-Stabilized Spray Flame by Halogenated Agents

July 28, 1996
Author(s)
Anthony P. Hamins, Cary Presser, L Melton
A series of experiments was conducted on baffle-stabilized spray flames in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame suppression. Measurements were made of the agent mass

Polymer Combustion and New Flame Retardants

May 20, 1996
Author(s)
Takashi Kashiwagi, Anthony P. Hamins, Kenneth D. Steckler, Jeffrey W. Gilman
The combustion of polymers is a complex coupled process characterized by energy feedback from a flame to the polymer surface and subsequent gasification of the polymer to generate combustible degradation products. Energy feedback characteristics for two

Heat Release Mechanisms in Inhibited Laminar Counterflow Flames (Journal)

January 1, 1996
Author(s)
Ki Y. Lee, Don J. Cha, Anthony Hamins, I K. Puri
Due to the participation of inhibitors in flame chemistry, it is difficult to concurrently characterize the complex interaction between their cooling action, and the chemical inhibition (which decrease temperature), and their contribution of heat release

THE INFLUENCE OF HALOGENATED FIRE SUPPRESSANTS ON THE COMBUSTION OF C1-C2 HYDROCARBONS

January 1, 1996
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., T Noto, Anthony P. Hamins, Wing Tsang, A W. Miziolek
Numerical simulations of the combustion of a number of fuels; (CH,, CH,OH, C2H,, GH, and C&J in air, in the presence and absence of fire suppressants, (CF,Br, CFJ, CF,, Cm3, GF6, and QF5H) have been carried out The simulations considered reactions in a

Suppression of Engine Nacelle Fires (NIST SP 890)

November 1, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary, P. Borthwick, N Gorchkov, Kevin B. McGrattan, Glenn P. Forney, William L. Grosshandler, Cary Presser, L Melton
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Suppression Criteria in Engine Nacelle Fires

October 21, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Suppression of Ignition Over a Heated Metal Surface

September 10, 1995
Author(s)
Anthony P. Hamins, P. Borthwick, Cary Presser
The objective of this work is to investigate the effectiveness of various agents in suppressing flame ignition. Experiments were conducted to determine the amount of agent needed to suppress the ignition of a gaseous propane flow over a heated metal disk

Volume Rendering of Pool Fire Data

July 1, 1995
Author(s)
H. Rushmeier, Anthony Hamins, M Y. Choi
In a pool fire, an ignited puddle or pool of liquid fuel burns in the atmosphere. Understanding pool fires is important to devising methods to control the hazards resulting from spilled fuels. In this case study we consider techniques for visualizing the

Characteristics of Pool Fire Burning

June 20, 1995
Author(s)
Anthony P. Hamins, Takashi Kashiwagi, R Buch
The structure and energetics of hydrocarbons burning in a pool fire configuration are reviewed. Examples of non-hydrocarbons are also presented. The character and structure of pool fires are discussed with special regard to the flame shape, flame pulsation

Tomographic Reconstruction of the Local PDFS of Soot Volume Fraction and Temperature

April 23, 1995
Author(s)
Y. R. Sivathanu, Anthony Hamins, Robert Hagwood, Takashi Kashiwagi
Deconvolution of local properties from line-of-sight measurements is important in a wide variety of applications such as x-ray tomography, nuclear magnetic resonance imaging, atmospheric sciences, optical inteferometry and flow field diagnostics. The Radon
