“…They conducted experiments on gasoline and diesel oil pool fires with diameters of 0.13 m, 0.18 m and 0.5 m. From this experimental data, they extrapolated the results to a pool diameter of 1 m and inferred that the emissivity would be close to one (less than one). However, this is in contrast with the conclusions made by Chatris et al [5] who stated that the data from small-scale fires cannot be extrapolated to largerscale pool fires.…”

“…However, for diameters greater than 2 m, mass burning rates were observed to be reasonably constant. Chatris et al [5] also measured mass burning rates for gasoline and diesel oil pool fires with diameters 1.5 m, 3 m and 4 m. For the two fuels studied, the increase in burning rate as a function of pool diameter approaches a constant burning rate for pool diameters about 3 m to 4 m. Hence, they considered the mass burning rate of pool fires with diameter 4 m as the mass burning rate of infinite diameter.…”

Flame emissivity is an important parameter in the study of pool fires. A series of pool fire experiments are carried out with four different fuels namely diesel, gasoline, hexane and kerosene for pool diameters of 0.10 m, 0.13 m and 0.20 m. Flame emissivity at a height of 0.25 times the pool diameter from the base is measured by observing the flame with reference to a black body using infrared camera. Influence of pool diameter (0.3 m, 0.34 m, 0.5 m, 0.7 m and 1.0 m) on flame emissivity at a height of 0.25 times the pool diameter is studied with diesel as the fuel. Variation of flame emissivity with the height of the flame along the center of diesel pool fire is investigated for diameters of 0.3 m, 0.5 m, 0.7 m and 1.0 m. It is observed that the flame emissivity is less at the tip of the flame in comparison with that at the base of the pool fire. The measurement of flame emissivity by observing flame with reference to a black body using infrared camera is corroborated with the measurements conducted with reference to an electrically heated black body for diesel pool fires with diameters 0.3 m, 0.5 m and 0.7 m. Flame emissivity is also inferred from the mass burning rate measurements for diesel oil pool fires of 0.3 m, 0.5 m, 0.7 m and 1.0 m diameters. Flame emissivities are independent of the measurement method. Temperature and surface emissive power distributions of the diesel pool fires for diameters 0.3 m, 0.5 m, 0.7 m and 1.0 m are computed using infrared thermography.

“…The process industries and the transport of hazardous materials are associated with the occurrence of different accidents, such as pool fires after an accidental fuel spill [3,4]. The analysis of these accidents showed that among the various possibilities (release, fire, explosion, toxic cloud), fire is the most common [5]. The fires cover 28% of all accidents, and the studies reveal that pool fires are one of the most frequent in the chemical industries [3,4].…”

The effects of pool diameters, height, fuel type, and presence of nanoparticles on flame temperature are tested. Nanoparticles were added and mixed with the fuel and its effect on flame spread time over the liquid fuel surface is studied. The results showed that pool diameter has the maximum effect on the increase of flame temperature. Nanoparticles reduce the flame temperature from 10 to 20% while flame spread time is increased 15% to 30% for kerosene and 6% to 26% for diesel oil. Experimental measurement of flame temperature distribution in a pool fire is carried out. Statistical analysis of flame temperature, flame spread time was made using Yates and ANOVA methods.

In this article, experimental measurements of flame temperature profile on a cylindrical tube circumference engulfed in a small‐scale pool fire were carried out. Three models were presented for flame temperature distribution with analytical and numerical based methods. The first model that is based on correlation showed the best agreements with experimental data, and other two models had almost acceptable predictions. The results revealed that the analytical and mathematical based model is more general than correlation methods and may be used to predict flame temperature and have wider‐range application usage.
