摘要
建筑火灾区域模拟的核心有两部分:建立火灾发展过程中各个现象的数学模型;通过求解数学方程式得到室内压力、温度和烟气层高度等火灾参数。后者是进行区域模拟软件编制以及火灾风险评估的核心,尤其是压力方程的求解,压力是求解其它参数的前提。给出了压力方程的求解思路,以单室火灾为例介绍了压力求解的具体方法,验证了计算结果的正确性。
The core task of building fire zone modeling has two parts: Establishing mathematical model for every phenomenon existing in course of a fire, and calculating some fire parameters such as compartment pressure, temperature, and height of smoke layer through solving equations. The latter is the core of zone simulating programming and fire risk assessment, especially the solving of pressure equations. Solving of pressure (equations) is the premises of solving other parameters. This paper presents the method of solving pressure equations and especially introduces detailed method for solving pressure equations of single compartment fire. Finally, verification of the results is made.
