在缩比室内进行了密闭空间火灾的实验模拟。根据火源特性的变化，考虑不同火源区域和不同燃料类型，研究了火灾发展过程和轰燃临界条件。对于这些实验的情况下，平均上层温度和温度波动的配置文件进行了测量。从两个通风口的质量流量进行了广泛的讨论。基于非线性动力学模型，建立了无量纲的室内火灾发展模型。对轰燃发生的临界判据进行了修正，指出能量增益率和能量损失率在燃料控制火灾和通风控制火灾的转折点相交。最后，将模型的模拟结果与实验数据进行了比较，并给出了轰燃与不轰燃的临界边界。结果表明，除聚乙烯存在较高的燃料特性数δ值外，理论预测与实验结果基本一致。
Experimental simulations of confined compartment fires are conducted in a reduced-scale compartment. Different areas of fire source and different types of fuel are considered in order to investigate the fire growth process and critical condition for flashover according to the changeable fire source characteristics. For these experimental cases, profiles of mean upper layer temperatures and temperature fluctuations are measured. The mass flow rate out from two vents is extensively discussed. A dimensionless model of this compartment fire growth is developed based on the nonlinear dynamics model. The critical criterion for flashover to occur is revised later, which shows that the energy gain rate and loss rate intersect at the turning point of fuel controlled fire and ventilation controlled fire. Finally, the simulation results of the model are compared with experimental data and the critical boundary between flashover and nonflashover is illustrated to show that the theoretical prediction reasonably agreed with experimental results except for polyethylene, where a higher value of fuel property number, δ, existed.
