Abstract

The flame height of the IFW was found to increase with the burning rate of the pool fire. Semi-empirical formula for flame height in the IFW was studied analytically in this paper using reported experimental data from full-scale burning tests. Burgers vortex theory was applied for dynamic and thermodynamic corrections. From the experimental data, a rotating flame height coefficient was introduced to modify the empirical formula for the flame height in the IFW. Effects of thermal radiation and fuel vaporization were included to modify the calculation of the fuel burning rate.
