Burning Characteristics Of Heptane In 2.7m Square Dike Fires

Abstract

An experimental study was made to explore the burning characteristics of heptane in 2.7m square dike fires, through measuring burning rate, flame temperature, thermal radiation, hot gas velocity and gas composition of flames. Two types of dike fire experiments were performed; one was a dike fire with four open top tank fires and another was a dike fire without tank. The results show that there is little difference between both types regarding total mass burning rate and thermal radiation, but it was noted that burning in the dike fire with open tanks was accelerated in spite of poorer air entraimnent than that of the dike fire without tank based on the gas composition data and the ratio of air entrainments A/Ao.

Numerical prediction of fire dynamics and the safety zone in large‐scale multiple pool fire in a dike using flamelet model

“…Both cases of no wind and the worst‐case scenario (a significant fuel loss under severe weather conditions) are considered for calculating safety distance. The CFD‐predicted results in calm wind conditions are compared with the experimental data of Koseki and Yumoto [ 8 ] and found to be in close agreement.…”

“…The CFD‐predicted grid‐independent results (flame temperature and O 2 and CO 2 mass fractions) are validated with the experimental data. [ 8 ] The validated results are further processed for predicting the safe zone surrounding the fire along with the quantification of pollutants. Both cases of no wind and the worst‐case scenario (a significant fuel loss under severe weather conditions) are considered for calculating safety distance.…”

Flame Height From Rectangular Fire Sources Considering Mixing Factor

“…We apply the same idea, expressed in equation (6b), to a flame merged from four pool fires that Koseki and Yumoto [13] have reported. They made a flame merged from four circular heptane pool fires in a dike, and obtained about 3m flame height from a pool fire source of 0.6m diameter, and merged flame height of about 5m from four pools, with a regression rate enhancement of 1.89 for each fire source.…”

An Experimental and Numerical Study of the Effects of Design Parameters on Water Mist Suppression of Liquid Pool Fires.

“…Finally, there are a number of large scale liquid pool fire studies [17][18][19] where fire suppression was not the objective. Rather the focus was on studying the burning characteristics and heat transfer processes in large scale pool fires.…”

“…A recent review by Hamins et al [17] discussed the structure and energetics of hydrocarbon pool fires with special emphasis on flame height, flame shape and flame pulsation frequency. Koseki and Yumoto [18] investigated the burning characteristics of 2.7m square dike heptane fires with and without open tank fires. The study was motivated by the need to mitigate the dangers of oil storage facility fires.…”
