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.
