| 摘 要： | 当前对于竖直向上屏障射流火的研究大多集中于顶棚射流，对于竖直向上射流火羽流撞击管道的研究相对较少。为研究竖直向上射流火羽流撞击管道的特征演化行为，基于燃烧学及流体力学基本原理，运用Fluent数值模拟软件，通过控制变量法对不同热释放速率、障碍管道直径及管壁-火源间距因素进行探究。研究表明障碍管道直径和管壁-火源间距对火焰高度和宽度均有一定程度的影响，且得到了基于Froude数的无量纲火焰高度表征模型。

| Abstract: | For the vertical upward barrier jet fire, the predecessors mostly studied the ceiling jet, but there were very few studies on the vertical upward jet fire plume impinging on the pipeline. In order to study the evolution behavior characteristics of the vertical upward jet fire plume hitting the pipeline, based on the basic principles of combustion and fluid mechanics, the influence of different heat release rates, diameters of the obstacle pipelines and the distance between the pipe wall and the fire source were investigated by using the Fluent software. It is concluded that the diameter of the obstacle pipe and the distance between the pipe wall and the fire source have a certain degree of influence on the flame height and width, and a dimensionless flame height representation model based on Froude number is obtained. |
