Energetics of Small and Moderate-Scale Gaseous Pool Fires
Anthony P. Hamins
A series of measurements were made to characterize the global properties of moderate-sized pool fires steadily burning in a quiescent environment. A wide range of parameters were considered including lightly and heavily sooting hydrocarbon fuels (methane, propane and acetylene), burners varying from 0.1 m to 1.0 m in diameter, and total heat release rates from about 0.4 kW to 200 kW. These conditions yielded flames that were 0.1 m to 2 m in mean height. Measurements were made characterizing the time-averaged mass burning rate and the distributions of radiative heat flux emitted. The data allowed determination of the fraction of the enthalpy released as radiation, a key global parameter characterizing a fire. The heat feedback to the fuel surface was modeled and compared to measurements. Hundreds of measurements were made in scores of experiments, which were distilled into a handful of time-averaged quantities per experiment.
