McCaffrey等估计轰燃前火灾温度方法的改进

Modification of McCaffrey et al's Method of Predicting Pre-flashover Fire Temperature

在估计室内轰燃前火灾温度的多种方法中,McCaffrey等人提出的方法比较典型。该文根据内衬材料的热惯性对室内火灾的重要影响,在大量实验数据的基础上,对McCaffrey等人提出的这一方法进行了初步和理论上的改进;结合室内火灾的控制因素,对有机玻璃火灾的回归结果进行了进一步改进,提出了估计室内轰燃前火灾温度的新方法。

Among various methods of predicting compartment preflashover fire temperature, McCaffrey et al' method is very typical. In this paper, according to the important effects of thermal inertia of lining materials on the behaviors of compartment fires, and basing on great mass of experimental data of compartment fires, McCaffrey et al's method was modified preliminarily and theoretically. In addition, combining with the control factor of compartment fires, the further modification of correlating results for the experimental data of PMMA fires was made, and a new method of predicting compartment preflashover fire temperature was put forward.
