摘要

建筑火灾区域模拟的工作核心有两部分: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。其中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

因为压力是求解其它参数的前提。本文给出了压力方程的求解思路

尤其以单室火灾为例介绍了压力求解的具体方法

最后验证了结果的正确性。

Abstract

The construction of fire zone modeling involves two crucial steps:: 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 by solving equations.The latter is the core of zone simulating programming and fire risk assessment

especially in solving pressure equations.The solution of pressures is the prerequisite for solving other parameters.This paper presents the method of solving pressure equations and especially describes the details of the method for solving pressure equations for single compartment fire.Finally

the validity of the present method is verified.
