Abstract:

The purpose of the program is to develop a methodology by which to define quantitatively the heat flux from fires of flame fuels burning under field conditions. Quantitative work during this period involved indoor flames of hexane and napalm test solvent in diameters of 11, 18, and 22 12 inches. Energy emitted in the visible region was compared with total radiant emission. Preliminary heat balances were conducted on the larger two sizes of flames each with the two fuels very good agreement was achieved. Heat balances also were made on fires subjected to artificial low-velocity winds, and spectra and burning rate were measured for gelled test solvent. The first lots of gelled fuel were prepared, and preliminary tests of the proposed explosive dissemination technique were conducted. Weather conditions prevented quantitative measurements on large outdoor fires. A system of foreoptics to provide either thermopile or spectrometer with a narrow field of view has been designed and is being fabricated. Difficulties resulting from fluctuations in flames, and the need for evaluating fuels under steady-state conditions by measuring heat release rates are discussed.
