Firebrands are a significant source leading to structures ignited and lost in large outdoor fires, such as Wildland-Urban Interface (WUI) fires, a large international problem, and urban fires, common in Japan. Sadly, hardly any information is available with regard to firebrand production from burning structures or actual large outdoor fires in general. To this end, an experimental database is being generated from firebrand generation from structure combustion. This paper will focus on how these detailed database results are being used to generate firebrand showers using a redesigned firebrand generator experimental apparatus installed in a full-scale wind tunnel, with the intent to experimentally simulate firebrand showers produced from structure combustion in large outdoor fires.

产生燃烧结构的风驱动火阵雨特征。

火把是导致建筑物在大型户外火灾中被点燃和损失的重要来源，例如荒地与城市交界处（WUI）火灾（一个重大的国际问题）和日本常见的城市火灾。遗憾的是，几乎没有任何关于燃烧建筑物或实际大型户外火灾产生火种的信息。为此，正在根据结构燃烧产生的火种生成实验数据库。本文将重点介绍如何使用安装在全尺寸风洞中的重新设计的火源发生器实验装置，使用这些详细的数据库结果来生成火源阵雨，目的是通过实验模拟大型室外火灾中结构燃烧产生的火源阵雨。
