Abstract
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 frequency, flame height, and the detailed flame structure. An enthalpy balance about the flame considers enthalpy losses to the surroundings due to radiation, convection of sensible heat, and combustion efficiency considerations. The power radiated from a flame as a function of burner diameter is discussed. An enthalpy balance about the pool surface partitions the heat feedback into conduction, convection, and radiation. This enthalpy is part of a positive feedback loop which goes to vaporize the fuel. Differences between field and zone models are discussed.
