超狭长两端封闭空间烟气运动工程分析方法的初步研究

Preliminary Study on Engineering Method to Predict Smoke Movement in Very Long-Narrow Spaces with Two Closing Ends

以CFAST4.02为模拟工具,发展了一种子空间划分的工程分析方法,来研究超狭长两端封闭空间内的烟气运动情况,还通过一个典型的算例来说明这种方法的有效性;为今后对类似空间的烟气运动工程分析提供了一定的思路和方法。

A new engineering method using CFAST4.02 was developed to predict the smoke movement in a very longnarrow space with closing two ends in this paper. Results show that this method can give more reliable smoke information than traditional simple twolayer method in such kind of spaces.
