Studies on fire behavior are extremely important as they contribute in a firefighting situation or even to avoid such hazard. Experimental studies of fire in real scale are unfeasible, implying that reduced-scale experiments must be performed, and results extrapolated to the range of interest. This research aims to experimentally study the fire behavior in tanks of 0.04 m, 0.20 m, 0.40 m, 0.80 m and 4.28 m diameter, burning regular gasoline or diesel oil S-500. The following parameters were here obtained: burning rates, burning velocities, heat release rates, flame heights, and temperature distributions adjacent to the tank. Such parameters were obtained for each tank diameter with the purpose of correlating the results and understanding the relationship of each parameter for the different geometrical scale of the tanks. Asymptotic results for larger tanks were found as (regular gasoline and diesel oil S‐500, respectively): burning rates 0.050 kg/(m² s) and 0.031 kg/(m² s), burning velocities 4.0 mm/min and 2.5 mm/min, heat release rates per unit area 2200 kW/m² and 1500 kW/m², normalized averaged flame heights (H_i/D, where H_i is the average flame height, D is the tank diameter) 0.9 and 0.8. Maximum temperatures for gasoline pools were higher than for diesel oil pools, and temperature gradients close to the tanks were also higher for the former fuel. The behavior of the maximum temperature was correlated as a function of the tank diameter, the heat release rate of each fuel and the dimensionless distance from the tank.

储罐直径对汽油和柴油储罐火灾热行为的影响

关于火灾行为的研究非常重要，因为它们会在灭火情况中发挥作用，甚至避免此类危险。在实际规模上进行火的实验研究是不可行的，这意味着必须进行缩小规模的实验，并将结果外推到感兴趣的范围。本研究旨在通过实验研究直径为0.04 m，0.20 m，0.40 m，0.80 m和4.28 m的普通汽油或柴油S-500的储罐的着火行为。在此获得以下参数：燃烧速率，燃烧速度，放热速率，火焰高度和与储罐相邻的温度分布。为了使结果相关和了解每个参数对于不同几何尺寸的罐的关系，针对每个罐直径获得了这样的参数。²  s）和0.031 kg /（m ²  s），燃烧速度4.0 mm / min和2.5 mm / min，单位面积放热率2200 kW / m ²和1500 kW / m ²，归一化平均火焰高度（H _i / D，其中H _i是平均火焰高度，D是储罐直径）0.9和0.8。汽油池的最高温度比柴油池的最高温度高，并且对于前一种燃料，靠近油箱的温度梯度也较高。最高温度的行为与油箱直径，每种燃料的放热率以及与油箱的无量纲距离有关。
