The present paper investigates a travelling fire scenario in an elongated structure (Length 18 m × width 6 m × height 3 m) with a controlled fire source of six trays filled with diesel (width 4 m × length 0.5 m). The fire spread is controlled manually by initiating fires consecutively in the pools. Fire dynamics simulator (FDS) is used to a-priori investigate variations in geometry, material data and fire load, whereas simulations using the final design and measured heat release rates (HRR) were performed after the test. The input to the model beside fire source and geometry are thermal material data. The FDS simulations were used to determine the appropriate size of the downstands (2 m from the ceiling in the final design) on the side to create a sufficiently one-dimensional fire spread. The post-test simulations indicate that although there are a lot of variations not included in the model similar results were obtained as in the test.

大型细长隔间中移动火灾的 FDS 模拟和建模工作

本论文研究了一个细长结构（长 18 m × 宽 6 m × 高 3 m）中的移动火灾场景，其火源为六个装有柴油的托盘（宽 4 m × 长 0.5 m）。通过在水池中连续点火来手动控制火势蔓延。火灾动力学模拟器 (FDS) 用于先验研究几何形状、材料数据和火灾载荷的变化，而使用最终设计和测量的热释放率 (HRR) 的模拟是在测试后进行的。除了火源和几何体之外，模型的输入是热材料数据。FDS 模拟用于确定侧面的下支架（在最终设计中距离天花板 2 m）的适当尺寸，以产生足够的一维火势蔓延。
