- Abstract
- The heat flux to the surface of a pool fire and the mass flux vaporizing from the pool are part of a positive feedback loop. The rate of mass burning depends on the heat feedback from the flame to the fuel surface and the mass burning rate controls the total heat release and the amount of heat feedback. Heat feedback, Q (W), to the pool surface is due to the sum of conduction, convection, and radiation. An energy balance at the fuel surface necessitates that the heat feedback is equal to the energy needed to vaporize the fuel and to overcome heat losses via re-radiation by the fuel surface to the surroundings, increased sensible heat of the liquie pool, and heat flux to the bottom and sides of the pool burner.
