| 摘 要： | 本文利用自行建立的油罐火灾燃烧特性通用模型,计算得到了燃烧速度、火焰高度,火焰跳动频率和平均温度等油罐燃烧特性的变化规律,并深入探讨了油品燃烧速度在油罐直径、风速、环境温度和油位等因素影响下的变化趋势。为了验证理论计算的准确性,将计算结果与汽油和柴油储罐的燃烧实验数据进行了对比,获得了较为满意的结果。

| Abstract: | Using the global model for the oil tank fires developed by authors, the variation of the burning characteristics, such as the burning rate, the flame height, the flame pulsation frequency, and the mean flame temperature were obtained. The influences of tank diameter, wind velocity, ambient temperature and the oil level on the burning rate were further discussed. In order to validate the theoretical solutions, it was compared with the experimental data of gasoline and diesel oil tank fires, and a good agreement is obtained. |
