摘要： 为研究集装箱香蕉水燃料火灾行为特征及影响因素，设计了集装箱门全部敞开、半开、全部封闭三种开口状态，火源位于集装箱浅部、中部、深部、角落四种不同位置，以及三种风向六种风速条件时的集装箱火灾场景。FDS模拟结果表明，开口状态和火源位置对火灾的热释放速率、燃烧速率和外部集装箱的温度影响较大，环境风变化的影响较小。远离火源位置烟气温度的升高和最大值出现时间都有一定的滞后。各工况下火源中心平均温度呈现明显的阶段性特征，纵向整个切面上部区域温度较高，下部温度较低。不同因素对火源中心平均温度演变的影响程度为：火源位置>开口状态>风速风向。研究结果对集装箱火灾的预防以及灭火具有非常重要的指导意义。

Abstract: In order to study the fire behavior characteristics and influencing factors of banana water fuel in containers, container fire scenarios were designed under three opening states of the container doors (fully open, half open, and fully closed), four different positions of the fire source (shallow part, middle part, deep part, and corner of the container), and six wind speeds under three wind directions. The simulation results of FDS show that the opening state and the position of the fire source have a greater impact on the heat release rate, burning rate, and the temperature of the external container of the fire, while the impact of environmental wind changes is relatively small. There is a certain lag in both the rise of the smoke temperature and the occurrence time of the maximum value at positions away from the fire source. The average temperature at the center of the fire source under each working condition exhibits obvious stage characteristics, with a higher temperature in the upper area of the entire longitudinal section and a lower temperature in the lower area. The degree of influence of different factors on the evolution of the average temperature at the center of the fire source is as follows: position of the fire source > opening state > wind speed and direction. The research results have very important guiding significance for the prevention and extinguishing of container fires.
