火灾通过辐射、火焰接触和引火物蔓延。虽然众所周知，火源阵雨是引起远离主火锋的点火的原因，但在短距离点火的情况下，来自主火的辐射可能在火源引起的点火过程中发挥作用。过去的许多研究都集中在对火灾蔓延的单一影响上，而对耦合影响知之甚少。通过使用新开发的实验方案，研究了辐射热通量和火源阵雨对燃料床点火过程的耦合影响。新开发的协议包括在与风力设施耦合的火种发电机的现有实验装置中添加辐射板。实验是在应用风场下进行的，因为风是大型室外火灾蔓延过程的关键参数。结果表明，辐射热通量在6 m/s以下对火火着火起重要作用，而在8 m/s以下则影响不大。
Fire spread occurs via radiation, flame contact, and firebrands. While firebrand showers are known to be a cause of spot fires which ignite fuels far from the main fire front, in the case of short distance spot fires, radiation from the main fire may play a role for firebrand induced ignition processes. Many past investigations have focused on singular effects on fire spread, and little is known about coupled effects. The coupled effect of radiative heat flux and firebrand showers on ignition processes of fuel beds is studied by using a newly developed experimental protocol. The newly developed protocol includes the addition of a radiant panel to the existing experimental setup of a firebrand generator coupled to a wind facility. Experiments were performed under an applied wind field, as the wind is a key parameter in large outdoor fire spread processes. Results show that radiant heat flux plays an important role for ignition by firebrands under 6 m/s while little effect was observed under 8 m/s.
