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.
飞火是导致大型户外火灾中建筑物被点燃并烧毁的一个重要源头，比如野地与城市交界处（WUI）火灾（这是一个重大的国际性问题）以及日本常见的城市火灾。遗憾的是，关于燃烧建筑物或一般实际大型户外火灾产生飞火的信息几乎没有。为此，正在通过建筑物燃烧产生飞火来建立一个实验数据库。本文将重点介绍如何利用这些详细的数据库结果，通过安装在全尺寸风洞中的重新设计的飞火发生器实验装置来产生飞火阵雨，旨在通过实验模拟大型户外火灾中建筑物燃烧产生的飞火阵雨。
