Abstract Having explained the characteristics of a corner fire in the configuration of Single Burning Item (SBI) test in Part I [1], the results of three flame spread experiments conducted with Medium Density Fiberboard (MDF) panels are discussed. The fire growth, in terms of flame heights and spread, is examined from two different angles visually and through Video Fire Analysis (VFA) with a flame detection algorithm. Total Heat Release Rates (HRR) and Smoke Production Rates (SPR), as well as total heat fluxes at several characteristic locations, are presented. Moreover, temperature evolutions are discussed for multiple locations and through the thickness of the panels. Also the backside temperatures, important as boundary condition for numerical simulations, are reported. The corner fire tests with MDF panels yield an average peak HRR of 151 kW and an average total heat flux exceeding 60 kW/m2 close to the burner, with average flame heights surpassing 1.5 m in about 60 s.

角落火灾的实验研究——第二部分：火焰在 MDF 板上蔓延

摘要 在第一部分 [1] 中解释了单燃烧项目 (SBI) 测试配置中的角落火灾特征后，讨论了使用中密度纤维板 (MDF) 面板进行的三个火焰蔓延实验的结果。在火焰高度和蔓延方面，从两个不同的角度直观地检查火灾的增长，并通过带有火焰检测算法的视频火灾分析 (VFA) 进行检查。提供了总热释放率 (HRR) 和烟雾产生率 (SPR)，以及几个特征位置的总热通量。此外，还讨论了多个位置和面板厚度的温度变化。还报告了背面温度，作为数值模拟的边界条件很重要。
