狭长空间火灾区域模型研究

计算机仿真模拟方法在性能化防火设计中扮演重要角色。区域模型方法有其独有的优势,其对计算机硬件要求较低,计算结果与实验结果符合的较好。以CFAST为代表的区域模型方法软件得到了广泛应用。CFAST被禁止应用于狭长空间的火灾模拟。通过对狭长空间进行一定的空间分割,得到了与实际基本相符的结果,从而进一步拓展了CFAST软件的使用范围。

A Fire Zone Model Method for Solving Narrow Space

The method of computer simulation plays a great role in fire performance- based design. Zone model has a special advantage: It requires lower computer hardware and computing result accords better with result of experimentation. So the method with zone model has become one of most common methods. CFAST, a typical model of zone software, has been applied in wide range. It is not permitted to apply CFAST in a narrow and long space, or else a distorted result will be got, but many such spaces need solving. According to the conditions. the simulating result has a nice match with the experimental result by the method of dividing space. So the extension of CFAST is broadened.
