| 摘 要： | 在建筑火灾的计算机模拟中,计算区域的选取密切关系到计算结果的合理性。已有研究针对单一开口小室在火灾燃料控制阶段和通风控制阶段时计算区域如何选取进行了分析并得到了定量的结论,该文在此基础上改进结果处理的方法,提出一种新的定量分析计算区域合理选取的方法,对单一开口小室在火灾两阶段间的过渡区域如何选取计算区域进行了定量分析。

| Abstract: | In building fire simulation, the selection of computational domain has an important effect on the rationality of simulation results. Previous researches have studies the method of selecting computational domain of one-vent compartment for fuel or ventilation controlled fire, with some quantitative conclusions obtained. In this paper, the method of processing results is further improved, and a new method for quantitatively analyzing the selection of computational domain is proposed, especially for the transition region between fuel controlled fire and ventilation controlled fire. |
